You need to prepare a C++ program to implement a user defined function.
Program: Write a C++ program that uses user-defined functions to read three integer numbers from the user, compute the summation, difference, and product of these numbers, and print the results on the screen.
Use only void functions (that pass parameters by value and reference, as needed). In particular, use
seven separate functions to do the subsequent:
Part 1: Prompt the user to enter three integer numbers. Use an appropriate message to ask the user to enter the numbers.
Part 2: Compute the summation of the numbers.
Part 3: Compute the difference of the numbers.
Part 4: Compute the product of the numbers.
Part 5: Print the summation of the numbers. Use an appropriate message to indicate that the result is an
addition.
Part 6: Print the difference of the numbers. Use an appropriate message to indicate that the result is a subtraction.
Part 7: Print the product of the numbers. Use an appropriate message to indicate that the result is a
multiplication.
All the given seven user-defined functions must be called in the main function.
