Thread: While statement

My program is working but is not displaying the correct results. It is displaying 5% instead of 2, 3, and 4 % for each year. If someone could tell me what I am doing incorrectly that would be fantastic.

Thanks in advance.


Here is my code

Code:

#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
int main()
{
    int principal = 1000;
    int years = 1;    //counter
    double balance = 0.0;
    double rate = 0.02;
        
    do //begin loop
    {
while (rate < .05)
rate = rate +.01;        
            




cout << "Year" << years << ":" << endl;






        {
            balance = principal * pow(1 + rate, years);
            //display rate with zero decimal places
            cout << fixed << setprecision(0);
            cout << "  Rate" << rate * 100 << "%: $";
            //display balance with two decimal places
            cout << setprecision(2) << balance << endl;


        }  //end for


    //years counter
years += 1;
}while (years < 6);


     


    //system("pause")
    return 0;
} //end of main function

Come on man, your code is all over the place. Edit your post and indent it properly, it's common courtesy and will increase your chances of getting help.

The incorrect code uploaded. I was in the middle of switching the statements. I did tweak parts of the rate. It now displays the years, but it only displays 3, 4 and 5 % and it is only displaying on year 1.

It should display
Year 1 through 5 with the rate %'s 2,3, and 4

This is the code.

Code:

#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
int main()
{
    int principal = 1000;
    int years = 1;    //counter
    double balance = 0.0;
    double rate = 0.02;
 
    do //begin loop

    {cout << "Year" << years << ":" << endl;



        while (rate < .05)
         { rate = rate +.01;


    //display rate with zero decimal places
            cout << fixed << setprecision(0);
            cout << "  Rate" << rate * 100 << "%: $";

        //display balance with two decimal places
            balance = principal * pow(1 + rate, years);
            cout << setprecision(2) << balance << endl;
          
        } // end while 
//years counter
years += 1;
    }
while (years < 6); 
    //system("pause")
    return 0;}
 //end of main function
