1. Write a program that calculates the final value of a ten year, $10,000 investment whose annual
return gradually declines from 2% to 1% over that term.
Solution
//Header file section
#include<iostream>
using namespace std;
//Program begins with a main function
int main()
{
//Initialize variables
double investment=10000, highIntrest=0.02,changeIntrest=0.01,years=10,result;
//prompt output
cout<<"Year "<<"Final_value "<<endl;
//Calculate the final value of a ten year
for(int i=1;i<=10;i++)
{
investment = (investment* highIntrest)+investment;
highIntrest=changeIntrest;
cout<<i<<"Â Â Â Â "<<investment<<endl;
}
cout<<"Final Value of a ten year="<<investment<<endl<<endl;
//Pause the system for a while
system("pause");
return 0;
}
