Question

In this module you learned about making loops in C++ and how to combine them with the material from the first few modules to solve problems.

For this assignment, you will write a C++ 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

input code:

output:

code:

#include <bits/stdc++.h>
using namespace std;

int main()
{
/*in this code i calculate increasing gym fees rate 2% of running year
not the previous year means after 1st year 2nd year rate will calculate as
secondyear_rate= firstyear_rate + 2% of firstyear_rate
thirdyear_rate= secondyear_rate + 2% of secondyear_rate*/
  
  
/*declare array for store the value*/
double increase_rates[3],rate=600;
/*compute the next three year gym membership fees*/
for(int i=0;i<3;i++)
{
/*increase fees 2% of that year*/
increase_rates[i]=rate+rate*0.02;
/*store that new year gym fees into rate */
rate=increase_rates[i];
}
/*write a loop for print the next 3 year Gym fees*/
for(int j=0;j<3;j++)
{
/*print the output*/
cout<<"Gym membership fees after "<<(j+1);
cout<<"th year is : $"<<increase_rates[j]<<endl;
}
return 0;
}
