Program:

Following is the C++ program to find the expected cost of an item in a specified number of years.

/*
* Program: The program asks the user to provide the value of the cost of the product, time in years and inflation rate to calculate the expected cost of the product.
*/
#include <iostream>
usingnamespacestd;
intmain(){
cout.setf(ios::showpoint);
cout.precision(2);
cout.setf(ios::fixed);
// Variable declaration
float cost;
cout<<"\nEnter the cost of the product: ";
//Variable declaration
cin>> cost;
// Variable declaration
inttime_in_years;
cout<<"\nEnter the time in years after which the product is purchased: ";
cin>>time_in_years;
floatinflation_rate;
cout<<"\nEnter the inflation rate: ";
cin>>inflation_rate;
floatinflated_rate= cost;
for(inti=1;i<=time_in_years;i++){
inflated_rate=inflated_rate+((inflation_rate/100)*inflated_rate);
}
cout<<"\nThe expected cost of the product is: "<<inflated_rate<<endl;
return0;
}

Explanation:

In the above program, a loop is used to find the expected cost of the product. Then cout() function is used to show the output of the program.

Sample Output:

Following is the sample output for the given program:

Enter the cost of the product: 100
 
Enter the time in years after which the product is purchased: 2 
 
Enter the inflation rate: 5.6 
The expected cost of the product is: 111.51
