Question

In this program, you will be using C++ programming constructs, such as functions.

main.cpp

Write a program that asks the user to enter an integer value. Your program will then display that integer back to the user.

Your program should include a function called getInteger that requests an integer value from the user and returns that value back to the caller.

Your main () function will call the function getInteger and will then display the value returned by that function.

Input Validation

You can either assume the user will always input a valid integer, or you can add input validation for the integer similar to the example shown in the midterm solution.

Hints

Be sure and define the function prototype before main () calls it.

Don't forget to add comments to explain what the code is doing and where control of the program is executing.

Choose variable names and function names that describe the purpose of the variable.

Sample Output

Enter an integer: 7

You entered 7

Answer 1

#include <iostream>

using namespace std;
//function prototype
int getInteger();
int main(){
//calling getInteger function to read integer value from user
   cout<<"You entered "<<getInteger();
}
//function to read integer from the user
int getInteger(){
//declared integer variable
   int n;
   //asking user to enter int value
   cout<<"Enter an integer: ";
   cin>>n;
   //returing the int value to user
   return n;
}
