Why am I getting an missing ')' identifier error in the following code?

Question

I'm trying to write a program that counts the number of perfect numbers within a limit, but the compiler keeps on giving me the "missing ')' before identifier 'num_squares'" error. Please help...

int main(void) {
 int num_squares = 0;
 int limit = 30;
 while(num_squares * num_squares < limit)
  num_squares++;

 printf("%d," num_squares);

}

Answer 1

Don't know about that part of the code, but you're missing a comma in your printf

printf("%d," num_squares);

should be

printf("%d,", num_squares);

Answer 2

You put comma inside ""-quotes in printf("%d," .

also please format your code.

Answer 3

use , after double qoutes in printf

Answer 4

This:

printf("%d," num_squares);

Should be:

printf("%d", num_squares);
