    Did you try searching the forum first? This is a fairly common question.

    If you happen to have any code that would be great. As Prelude suggested there are numerous ways to show binary data, you will just need to search for those and apply the ones that are best suited for your application, be it a binary data file or convertion to binary and back.

    Code:
      #include <stdio.h>
      int main(){
      int i, val = 1;
      for(i = 1, i < 35, ++i){
      printf("%15d%15u%15x%15o\n", val, val, val, val);
      val *= 2;
      }
      return 0;
      }
    This is what my assignment is, but I would like to go the extra mile and incorporate the binary display if I do an incremental val count in the loop

    Well your for loop needs to use ; and not a comma separator. Also your fourth val value in your printf statement should be renamed, and thus should be the output from another function that converts your decimal to binary, perhaps using a pointer to char to store your ones and zeros.

    What I mean is that you will need to call another function from within your for loop that will convert your 'val' value to binary. You will need to pass this value( in decimal if you like) and assign the output(char*) from this new conversion function to another value, call it binary.

    example

    Code:
    :
      printf("%15d%15u%15x%15s\n", val, val, val, binary);
      val *= 2
      dec_to_bin(val);
    }
      return 0;
    }
    
    char * dec_to_bin(int value)
    {
      char * value;
      :
        your code to convert;
      :
    
       return value;
    }
    As noted there are many functions out there and many ways to accomplish this. But this should get you going.

    Sorry, you will need to define binary. Suggest


    Code:
    char * binary;
    Then

    Code:
    binary = dec_to_binary(int val);  /* example only */

    Yes I searched first, and what I was looking for wasn't listed

    Ooh, that's such a lie. I've personally answered this question countless times, so you can't get away with telling me it's not there.
