C Programmers, please help with small program

[beggerking]

you need to add a ; after sum+=j

the paranthesis is recommanded but i dnt think its required.

So that gets rid of that error on that line, but I think we may have an extra braces... because i get an error

test.c: In function `main':
test.c:16: error: syntax error at end of input

Yea i added that ; already.

 

[beggerking]

try take out the ; after the last }

my bad, i guess the paranthesis is required

 

[Aznguy1872]

yup, need one more bracket of }

Ok i ran it, it compiles fine, but doesn't print anything so from the code below. SUM never = i..

#include <stdio.h>

int main (void) {
int i, j,SUM=0;
for (i=1;i<10000; i++) {
for (j=1;j<i; j++) {
if((i % j) == 0) {
SUM+= j;
}
if (SUM == i) {
printf("%d", SUM);
}
SUM = 0;
}
return 0;
}
}

 

[beggerking]

yes, add a } after sum+=j;
and delete the last }

should be like this

#include <stdio.h>

int main (void) {
int i, j,SUM=0;
for (i=1;i<10000; i++) {
for (j=1;j<i; j++) {
if((i % j) == 0) {
SUM+= j;
}
}
if (SUM == i) {
printf("%d", SUM);
}
SUM = 0;
}
return 0;
}
