We have to use C++ !!!

Problem G1

This program will read integers from a file and find results from these integers.

Open the file, test to make sure the file opened. Use a loop to read the integers and process each integer as it is read. When End Of File is reached, close the file.

After all of the integers have been read and processed, print the results for the following output:

• The integer count:
• The sum of the integers:
• The smallest integer:
• The largest integer:
• The average of the integers:

Use notepad, vim, or other simple text editor to create a file named file1.txt containing the following, with one integer per line.

Test the program two times.

Use the following data in the first test:

11 9 18 22 27 33 21 

For the second test add an additional line containing the number 40.

Problem G2

Write two functions: A function named sum which takes two integer values as arguments, and returns their sum. A main function which asks the user for two integer values, passes the two values to the sum function, then prints the two values and their sum. The main function then again asks the user for two integer values, passes the two values to the sum function, then prints the two values and their sum.

Test it once, with the values 3 and 4, and then 5 and 49.

Problem G3

The purpose of this problem is to write some small functions and practice passing things around amoung functions. 1) The main function shall ask the user to enter three numbers and read the three numbers. 2) Write a function named findSum that takes three numbers as arguments and returns their sum. The main function shall call this function. 3) Write a function named findAverage that takes the sum and the number of numbers and returns the average. The main function shall call this function. 4) Write a function named findSmallest that takes the three numbers and returns the smallest value. The main function shall call this function. 5) The main function shall print the results in the following format, with two decimal positions and the decimal points aligned:

Results: First number 17.23 Second number 3.98 Third number 22.32 Total 43.53 Average 14.51 Smallest 3.98 

Test the program twice with the following two sets of numbers:

37.144 2.4144 19 4.23 5.78 6.21
