Write a program that reads in 4 cards using the two letter abbreviation codes from the command line using argc and argv. Check to make sure you have the correct number of inputs on the command line before proceeding. (Your program must have a total of 5 arguments before it can perform the trick.) Each command line argument, must be converted to a std::string type variable. Use the at() method of the std::string class to access the value and suit of the inputted card. (Do not use the [] operators!) When using the at() method it will return a char type. Convert the char type to a string type. For example: string hello = "Hello World"; // The first letter is at position string letter_H = string(1, hello.at(@)); // The second letter is at position 1 string letter_e = string(1, hello.at(1)); // The letter d 1/ Get the size of the string, subtract 1 which will give the location of the last letter string last_letter = string(1, hello.at(hello.size() - 1)); When using at() you should wrap each usage with a try/catch just like the try/catch pattern learned from the previous lab to catch errors. string hello = "Hello World"; string letter_e; try { letter_e = string(1, hello.at(1)); }catch (const std::exception& e) { ErrorMessage(); 1/ exit will end the program abruptly and return 1 to the operating system. exit(1); Use the exit() function to exit from your program if an error occurs in a function. Remember to #include
to take advantage of the exit() function. If you need to use std::stoi() to convert a string to an integer. Use the try/catch pattern learned from the previous lab to catch errors. Write a function which will convert a string which represents a card's value to an integer. Remember that a card can have the numerical value of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 yet the values are represented by strings "A", "1", "2", "3", "4", "5", "6","7", "8", "9", "10", "J", "Q", "K". Handle the exceptional cases "A", ")", "Q", and "K" by mapping those strings onto the integer values 1, 11, 12, and 13 and use stoi() for all the other cases. Always use try and catch with stoi() to catch errors. The functions prototype is int CardValue(const string& string_value); - Write a function which will convert an integer value to a card's string value. The function prototype is string IntCardValueToString(int value); . The input is an integer such as 1 and it returns a string 'A'. If the value doesn't need to be converted to a letter, use the to_string() function to convert from an integer to a string. Write a function which will calculate the secret card's value. The function prototype is int SecretCardValue(int base_value, int steps); . You may find that converting a cards value from a string to an integer is best done by writing many if and else-if statements. Write a function that will return what value to add to the base card given the three other cards inputted. The function prototype is int SecretSteps(const string& card_one, const string& card_two, const string& card_three); . If two or more cards have the same value, use the card's suit to determine the order. The function SecretSteps() has very complicated logic if we mix integer values with string suits. Instead, write a function named SuitMultiplier() which maps a given card into a numerical range. For example, all the clubs will be the values 1 through 13, all the diamonds will be 14 through 26, all the hearts will be 27 through 39, and all the spades will be 40 through 52. This way, comparing the three cards given to SecretSteps() is straightforward. The function prototype is int SuitMultiplier(string suit); . The function takes a suit as a parameter and returns the starting index of that suit. Write a function void ErrorMessage(); which prints out "This program may only be used by a qualified technician. " whenever an error is encountered. Exit with a return status of 1 when there is an error.
