Question

This is for an intro to C++ class, and this module is an introduction to looping for C++. If you have any additional question please let me know.

"For this assignment, you will write a program that calculates a rate increase for a gym membership. Consider the following scenario:

A gym membership, which currently charges $600 per year for membership, has announced that it will increase its membership fee by 2 percent each year for the next three years.

Write a program that uses a loop to display the projected rates for the next three years. Be sure to include comments throughout your code where appropriate."

Answer 1

#include <iostream>
using namespace std;

int main()
{
float currentcharge = 600; //assign the current membership fee value to 600;
cout<<"\nCurrent membership fee is: "<<currentcharge; //print the current value
int i;
//loop the process for three years to calculate it's value for next 3 years.
for(i=1;i<=3;i++)
{
currentcharge = currentcharge*1.02;
//we are multiplying with 1.02 because we are
//increasing the value by 2% which means currentcharge*(1+2/100)
//which is currentcharge(1+0.02) which is currentcharge(1.02)
cout<<"\nMembership fee for year "<<i<<" is: "<<currentcharge; //print the value
}
return 0;
}

OUTPUT:
