The previous program used a loop that iterated 40 times to calculate that.
Here is the part from the previous program (slightly modified) that calculates the number of dollars after 40 years:
year = 1 ; dollars = initialAmount; // initialize the loop correctly while ( year <= 40 ) { dollars = dollars + dollars*rate ; // add another year's interest dollars = dollars + 1000 ; // add in this year's contribution year = year + 1 ; }
Here is the skeleton program again:
To complete the program you will have to nest one loop inside the other.
Copy and paste sections of code.
