Thread: bull, I got a "bus error"

this program is supposed to take in 2 numbers and then displays their product or sume, depending on what the user selects.

so check this code out please

Code:

#include <stdio.h>

int main()
{ int num, num2, check, output;
 
  printf( "put in an integer by brother: " );
  scanf( "%d", &num );
  printf( "put in another and we either sum these two or multiply them soon:" );
  scanf( "%d", &num2 );
  
  printf( "do you want it multiplied or summed?  if you want it to be multiplied type in 1, if you want to divide type 2: " );
  scanf( "%d", check );
         
  if ( check == 1, output = num * num2 )
     printf( "%d", output);
  else if ( check == 2, output = num + num2 ) 
     printf( "%d", output);
  else printf( "you musta done something wrong" );
  return 0;
  }

and by the way, what does a "bus error" usually imply if anthing at all? hmmm, time to search while I wait for help, but you can tell me something any book could so don't hesitate, I hope you tell me that is.

oh, woops.

oh, and use the braces on that if statement, i got it and that makes sense. sorry, it just didn't click, and I have done this before. thanks.
