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 ] tags
 
thank you

ok, not a problem. C users will post them for you here 😉. By the way will Java programs work for you?

What biggie meant was, can you try typing the basic C structure first (eg the "#include" preprocessor directive)? 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 only wanted him to try. Once you know the formula for generating perfect numbers; rest is cakewalk.

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

Even I also don't wanted to give him/her ready made program but I don't even want to give him/her a bad impression from this forum in the starting itself. I want him/her to be more active.😀

Hey abbd1990, check these two small programs. Are these two what you wanted? 😀


Write a program that outputs all perfect numbers less than 1000
/*
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;
}
