In C++ I only need the final code. Pleaseee include srand() statement !!! This program will ask the user to answer a series of arithmetic problems and report on how the user performs. You will write this program in phases as specified below. Make sure that each phase works correctly and uses good style before progressing to the following phase. The purpose of this assignment is to give you lots of practice with parameter passing without making you write a huge program. For this reason you must adhere to the following structure diagram. If you fail to do this, you will receive a 0 on the assignment. Each box represents a function that you will have in your program. It includes every function that you will have in your program. You should have no more and no fewer, and you should use the exact names that have been indicated here.

The functions won't make sense just yet. You'll need continually refer back to this diagram as you work your way through the phases. structure diagram Structure Diagram Notes: The doOneProblem function does exactly one problem, not one *type* of problem! This function will perform all of the tasks involved in finishing one complete problem, including printing the problem, checking the answer, etc. CheckAnswer is the function that writes either "correct" or "incorrect" You will receive a 0 on this assignment if you use global variables, arrays or structs You will lose points if the code you put in one of your functions does not correspond to the name of the function given in the structure diagram. Do not use value returning functions in this assignment. The purpose of this assignment is to give you practice with parameter passing, including pass-by-reference, and you could miss much of this experience if you use value returning functions instead. Definitions: As a quick review of arithmetic, make sure you are clear that the "operands" in an expression are the things that appear on either side of the operator (numbers in this case). Don't get that mixed up with the operator. The operators are +, -, and *. Phase 1: Your main() function for phase 1 must look exactly like this: int main() { srand(static_cast(time(nullptr))); // comment this out to submit to zyBooks doOneSet(); } Important Submission Note: Before you submit your code to zyBooks, comment out the srand() statement. This will ensure that you get the numbers for the problems that zyBooks is expecting. You must write the function doOneSet which will, for now, write out 5 addition problems. All of the numbers printed should be between 0 and 100, inclusive. Here is a sample output for this phase: 45 + 21 = 0 + 100 = 54 + 23 = 4 + 19 = 18 + 92 = The numbers that are produced for these problems must be generated randomly by the computer. The numbers in the sample output are given only as an example. Refer to lesson 7.3 for more information about generating random numbers. Phase 2: Change your doOneSet function so that instead of just writing out the problems it also allows the user to enter an answer, and then tells the user whether the answer was correct or not. Do not change your main() function. Here is the sample output for this phase (user input is indicated here by using bold font. It won't be bold in your own output): 45 + 21 = 66 correct 0 + 100 = 100 correct 54 + 23 = 67 incorrect 4 + 19 = 13 incorrect 18 + 92 = 110 correct Before you move on to phase 3, refer to the structure diagram above and make sure that you have adhered to it for all of the functions indicated there for phase 2. This will probably mean dividing your doOneSet function up into functions, if you haven't done it already. Phase 3: Now you will change your doOneSet function so that it will work for either addition, subtraction, or multiplication. For the purposes of this assignment, a set of problems is defined to be a group of problems that are all of the same type (all addition, all subtraction, or all multiplication). After completing this phase your program will give 5 addition problems, 5 subtraction problems, and 5 multiplication problems, for a total of 15 problems. Your main() function must look exactly like this: int main() { srand(static_cast(time(nullptr))); // comment this out to submit to zyBooks doOneSet('+'); doOneSet('-'); doOneSet('*'); } The parameter tells doOneSet whether to do addition, subtraction, or multiplication. Notice that there is exactly one doOneSet function definition, not three! At this point students often have trouble writing the parameter list for doOneSet. As a hint, remember that a parameter is simply a declaration statement, and that the number and type of a function's arguments must match the function's parameters. Here is the sample output for this phase: 45 + 21 = 66 correct 0 + 100 = 100 correct 54 + 23 = 67 incorrect 4 + 19 = 13 incorrect 18 + 92 = 110 correct 59 - 19 = 40 correct 19 - 84 = -29 incorrect 0 - 65 = -65 correct 96 - 1 = 95 correct 94 - 14 = 80 correct 0 * 87 = 0 correct 45 * 84 = 398 incorrect 8 * 37 = 873 incorrect 34 * 83 = 831 incorrect 38 * 3 = 238 incorrect Phase 4: Now you are ready to let the user specify how many problems per set. (Recall that a set is a group of problems all of the same type. In this program we are doing three sets: one set of addition, one set of subtraction, and one set of multiplication. This means that, for example, if the problems per set is 7, there will be a total of 21 problems given.) Ask the user to enter the number of problems per set at the very beginning of the program, so that all three sets have the same number of problems per set. Now your main() function will look exactly like this except that you may add variable declarations in the indicated location: int main() { srand(static_cast(time(nullptr))); // comment this out to submit to zyBooks getProbsPerSet(probsPerSet); doOneSet('+', probsPerSet); doOneSet('-', probsPerSet); doOneSet('*', probsPerSet); } For this phase you should also add a header at the beginning of each set, as illustrated in the following sample output for this phase. For purposes of the header, you should assume that the addition problems will always be set #1, the subtraction problems set #2, and the multiplication problems set #3. Enter problems per set: 3 Set #1 ---------- 45 + 21 = 66 correct 0 + 100 = 100 correct 54 + 23 = 67 incorrect Set #2 ---------- 59 - 19 = 40 correct 19 - 84 = -29 incorrect 0 - 65 = -65 correct Set #3 ---------- 0 * 87 = 0 correct 45 * 84 = 398 incorrect 8 * 37 = 873 incorrect Phase 5: Now let the user specify maxNum, the maximum number to be used for each set. This means that instead of choosing numbers between 0 and 100 (inclusive) for each problem, the computer will be choosing numbers between 0 and maxNum (inclusive). You must allow the user to enter a different maximum number for each set. This won't change the main() function, since you need to ask it again before each set. It will be done near the beginning of your doOneSet function. Here's the sample screen output: Enter problems per set: 3 Set #1 ---------- What is the maximum number for this set? 100 45 + 21 = 66 correct 0 + 100 = 100 correct 54 + 23 = 67 incorrect Set #2 ---------- What is the maximum number for this set? 90 59 - 19 = 40 correct 19 - 84 = -29 incorrect 0 - 65 = -65 correct Set #3 ---------- What is the maximum number for this set? 20 0 * 18 = 0 correct 15 * 4 = 398 incorrect 8 * 17 = 873 incorrect Phase 6: Now you need to keep track of how the user is doing. after the user has attempted all of the problems, your program should write a report that says how many the user got right on each set out of how many and for what percent. The report must also indicate the overall figures. Here's a sample screen output: Enter problems per set: 3 Set #1 ---------- What is the maximum number for this set? 100 45 + 21 = 66 correct 0 + 100 = 100 correct 54 + 23 = 67 incorrect Set #2 ---------- What is the maximum number for this set? 90 59 - 19 = 40 correct 19 - 84 = -29 incorrect 0 - 65 = -65 correct Set #3 ---------- What is the maximum number for this set? 20 0 * 18 = 0 correct 15 * 4 = 398 incorrect 8 * 17 = 873 incorrect Set#1: You got 2 correct out of 3 for 66.7% Set#2: You got 2 correct out of 3 for 66.7% Set#3: You got 1 correct out of 3 for 33.3% Overall you got 5 correct out of 9 for 55.6% Note that the results must be rounded to the nearest tenth. To round your results, just use cout << fixed << setprecision(1) << yourPercentCorrectVariable; You'll also need to #include Technical note: some of you may notice that this method does not always round up on "5" as we are all taught to do in math. Don't worry about this. You can assume that the rounding that this method does is correct. Your main() function for phase 6 must look like this, except that you may add variable declarations and arguments in the indicated locations: int main() { srand(static_cast(time(nullptr))); // comment this out to submit to zyBooks getProbsPerSet(); doOneSet(); doOneSet(); doOneSet(); printReport(); } Since printReport() will be almost all cout statements, we will make an exception to the Style Convention about functions never being longer than 15 lines. But it should still come in under 20. Notice that you may send no more than 3 arguments to doOneSet. Hint: Although main() will need three separate variables to keep track of the number of problems answered correctly in each set, your doOneSet function will have only one parameter that keeps track of the number of problems answered correctly in the current set. It will be up to main() to get that information into the correct variable. More hints: Many students struggle with phase 6, so in case you get stuck, here are my suggestions for how to approach this: Start by writing the printReport() function. That way you will know exactly what parameters printReport() will need in order to do its job. Then work your way backward. In main(), in the call to printReport(), add the appropriate arguments to match printReport()'s parameters that you just determined. Then figure out how main() will get those values. (The only way main can get those values is to get them from doOneSet().) So, you'll have to edit doOneSet() so that it communicates the correct value back to main(). How will doOneSet() know what the correct value is? This will involve some work inside doOneSet(), but mostly it means that doOneSet() will need to get some information from doOneProblem(). And keep going, working your way backward. Important Submission Note: Before you submit your code to zyBooks, comment out the srand() statement. This will ensure that you get the numbers for the problems that zyBooks is expecting.
