Thread: unable to run program

This is your original program, made workable in TC AND in a modern C compiler. Note that the double quote char used in the print line, used angled double quotes, instead of straight ones. Angled double quotes simply do not work in any C compiler.

Code:

#include <stdio.h>

int mul (int x, int y); //prototype of the function

int main ()
{ 
    int a, b, c;

    a = 5;
    b = 10;
    c = mul (a,b);

  // Note that double quotes char is " NOT “ or ” those are NOT OK!
  //printf (“multiplication of %d and %d is %d”,a,b,c); <-----NOT GOOD!
  printf ("multiplication of %d and %d is %d\n",a,b,c); 

   return 0;
}
int mul (int x, int y) 
{
   int p;
   p = x*y;

   return(p);
}
