Thread: Help!!!

Hello - I am trying to figure out how to create a running total per year. The start total should be my previous ending year total. Can anyone help me figure out what I am doing wrong because I am clueless.
Thanks for the help

Code:

#include <stdio.h>

int main()
{
	 float amt = 1000;
     float percent = .08;
     int year = 0;
     float yeartotal = 1000;
     
     yeartotal=yeartotal+(amt*percent);

     printf("Year     Start    End\n");
     printf("-----    -----    ----\n");

	 for(year=1; year<=10; ++year)
     printf("%3d      %3.0f     %4.0f\n", year, amt, yeartotal*year);


     return 0;
}

This is what I get when I run my code.

Code:

Year     Start    End
-----    -----    ----
  1      1000     1080
  2      1000     2160
  3      1000     3240
  4      1000     4320
  5      1000     5400
  6      1000     6480
  7      1000     7560
  8      1000     8640
  9      1000     9720
 10      1000     10800

This is what it should look like.

Code:

Year     Start		  End
-----    -----		  ----
  1      1000.00     1080.00
  2      1080.00     1166.40
  3      1166.40     1259.71
  4      1259.71     1360.49
  5      1360.49     1469.33
  6      1469.33     1586.88
  7      1586.88     1713.83
  8      1713.83     1850.94
  9      1850.94     1999.02
 10      1999.02     2158.94

1 - Read the forum guidelines. "HELP!!!!" is not an appropriate title.
2 - You only get one output, because that's all your loop does. You need to make your loop actually change the values inside the loop. Not just once outside it.


Quzah.

Code:

for( x = 0; x < 10; x++ )
{
    y = y + 2;
    printf("y is now %d\n", y );
}

You don't do anything in your loop, other than print the same unchanging value over and over.

Look at your output. You're outputting the same exact variable for start and end. So you can't very well expect printf() to do anything that makes them different. So you have an assignment statement that changes the value of year total. But when do you want to do that statement?

Look at your code:

Code:

printf("%3d      %3.0f     %4.0f\n", year, yeartotal, yeartotal)
yeartotal=yeartotal+(yeartotal*percent);

Anyway you swap these two lines around, the last thing that's printed out before the assignment is yearend. Correct? But is that where you want to change your value? Look at your correct output:

Code:

Year     Start	     End
-----    -----       ----
  1      1000.00     1080.00
  2      1080.00     1166.40
  3      1166.40     1259.71
  4      1259.71     1360.49
  5      1360.49     1469.33
  6      1469.33     1586.88
  7      1586.88     1713.83
  8      1713.83     1850.94
  9      1850.94     1999.02
 10      1999.02     2158.94

What is the last output before the value changes?
