Question

chapter 7. Create a program that allows the user to enter the ages (in years) of five people. The program should display the average age. Use the for the statement. Display the average age with one decimal place. If necessary, create a new project named TryThis15 Project, and save it in the Cpp8\Chap07 folder. Enter the C++ instructions into a source file named TryThis15.cpp. Also, enter appropriate comments and any additional instructions required by the compiler. Test the program using the following ages: 23, 31, 37, 19, and 43. (The answers to TRY these Exercises are located at the end of the chapter.)

Answer 1

//Find attached SS of code and output. Comments are also included for help.

//Including header file iomanip is for input output manipulation
#include <iostream>
#include <iomanip>
//namespace declaration
using namespace std;
//main function
int main()
{
//data types declaration
int years[5];
float avg=0.0;
  
  
cout<<"Enter Age of 5 persons(in years): "<<endl;
// store input from user to array
for (int i = 0; i < 5; ++i) {
cin>>years[i];
}
  
//fixing output decimal precision to 1
cout<<setprecision(1) <<fixed;
  
//adding ages
for (int i = 0; i < 5; ++i) {
avg+= years[i];
}
//taking average
avg = avg/5;
  
//printing output
cout<<"Average Age is "<<avg;
  
return 0;
}
