My program is displaying.....actual hearts

I'm writing a program which takes a surname, and assigns a phonetic code to the name(SOUNDEX encoding)

Anyway, for certain names, the program is displaying a little 'heart' character instead of a number. There is nothing in the program directly instructing it to display a 'heart' character.
What normally causes this?

I don't want to display the code as it is coursework and I don't want direct help with the code.

Thanks

Attempting to print the character representation of an integer value such as 3 rather than the intended '3'.

Code:

---

#include <stdio.h>

int main(void)
{
  int value = 3;
  printf("%%d: %d, %%c : %c\n", value, value);
  value = '3';
  printf("%%d: %d, %%c : %c\n", value, value);
  return 0;
}

/* my output
%d: 3, %c : 
%d: 51, %c : 3
*/

Make sure you are initializing the variable that is holding this "heart" to zero. Like if it was a C-style string, it would be initialized like this:

Code:

---

char var[256]={0};

---

If it's not initialized to zero then it may have that junk in it.

You probably just have %c instead of %d (or %i, which is the same thing as %d).
