For Loop question

KRoNIC · 12-11-2008 07:58PM #1

// Loop: For n=1 to theNumberOfYears
// interestEarned equals principal times interest rate
// Accumulate the interest earned so far
// new balance equals previous balance plus interestEarned
// Print Out: Year# Interest New Balance
// End of Loop

can anyone write a sample code for this to help me please?
If this isn't enough information, let me know. I'll try to give more info.

for(n = 1; n <= numberOfYears; n++) {
}

For loops will look almost identical all the time. I didn't do the inside of the loop because its your homework.

Also is it java or c/c++ ?

Most of the seasoned programmers here can do that for you, but most won't until you show us what you have tried. And told us what language.

We don't do homework. But we will help with it.

My apologies.

Here is what I have so far.

String y, interest, d;
int years, i, dollars;
double interestEarned, newBalance;

(All the dataIn.readLine();
Integer.parseInt(); etc etc
......

for (int n=1; n<= years; n++) {
interestEarned = (dollars * i);
newBalance = (n + interestEarned);
System.out.println( n + " " + (newBalance) + " dollars");
} // end of loop

It is compiling successfully and I know that it is doing the "(dollars * i)" calculation correctly, but from that point on I am confused as to what to do next. The next instruction after "interestEarned equals principal times interest rate" says "Accumulate the interest earned so far", then "new balance equals previous balance plus interestEarned" which I attempted but don't think I did correctly.

1. you don't need to put the sums in brackets.

eg.

interestEarned = dollars * i;

2. n is basically a number. So n + interestEarned would be 1 + n + interestEarned, 2 + interestEarned, etc.

What you want to do is

newBalance += interestEarned;

3. Be aware that you are using ints. They do not have floating points.
