Join Date: 6th January 2009 I'm a Crazy Electrical Engineer | Help me with C programs Write a program that outputs all perfect numbers less than 1000 Write a program that inputs two fractions in the form a/b and c/d , and outputs their sum in the form p/q cancelled down to its simplest form ?
Everyone - please enclose the code in [code] ... [ /code ] tags
thank you |

Then we can see what area you are struggling at  You'll learn better if you show us your attempts.
Unless, you have no clue at all?

I'd still want him to post the incorrect program and ask CEans to guide him than looking for a ready-made program. |

I want him/her to be more active.

Write a program that outputs all perfect numbers less than 1000
| Code: /*
C program to display all perfect numbers less than 1000

#include <stdio.h>
#include <conio.h>
int main() {
int i,j,num,sum;
clrscr(); // To clear the screen
printf("The perfect numbers less than 1000 are:");
for(i=1;i<1000;i++) {
num=i;
sum=0;
for(j=1;j<num;j++) {
if(num%j==0)
sum=sum+j;
}
}
if(sum==num)
printf("\n%d",num);
}
getch();
return 0;
