Thread: Char to Binary

Does anyone know how to convert a character to the binary number in C. I need to get a character from the user and convert that character's value to the Binary number.

You can use a recursive function to do that, though it's very easy to convert it to an iterative version... here's an example:

Code:

void Bin( unsigned int n )
{
   if( !n )
      return;
   Bin( n/2 );
   printf( "%d", n%2 );
}

I don't think there's a standard library function that does that, but it's not difficult to write your own:

Code:

#include <stdio.h>

int main(void)
{
  int i, ch;
  char binary[9], *b = &binary[7];

  printf("Enter the character: ");
  scanf("%c", (char *)&ch);

  for(i = 1;b >= binary;i <<= 1)
    *b-- = (ch & i)?'1':'0';
  binary[8] = '\0';
  puts(binary);

  return 0;
}

Thanks alot itsme86 and Vber that information you have given to me was very useful thanks a lot.
