## Simple binary problem

Hello guys, I want to convert decimal from dec_buffer to a bin_buffer.

Example: dec_buffer=1; bin_buffer={000000000001};

dec_buffer=2; bin_buffer={000000000010};

dec_buffer=3; bin_buffer={000000000011};and soon

The error is at "bin_buffer[buf_num] = show_binary(dec_buffer[buf_num]);" ; Error: incompatible types in assignment

I think it's a newbie question since I am a newbie on C programming, so please give me a hint :)

NB:If there's any undeclared constant, please ignore it since i didn't copy all of my code here. I copied the part with issues only.

```# include <stdio.h> # define BUFFER_NUM_MAX 192 //16*12# define BIT_NUM_MAX 12 //12bit int dec_buffer; int bin_buffer; int bit_num; int buf_num; int show_binary(int num){ int j,b={0}; printf("data converted: %d ; binary: ",num); for (j=1;j<=BIT_NUM_MAX;j++){ b=num%2; num=num/2; } for(j=0;j<BIT_NUM_MAX;j++){ printf("%d",b); } printf("\n"); return b; } int main(void){ for (buf_num=1;buf_num<=BUFFER_NUM_MAX;buf_num++){ dec_buffer = buf_num; bin_buffer = show_binary(dec_buffer);//Error: incompatible types in assignment } ```

If it's about the different array dimension, I have tried below code,but no luck.

``` int show_binary(int num){ int j,b; printf("data converted: %d ; binary: ",num); for (j=1;j<=BIT_NUM_MAX;j++){ b=num%2; num=num/2; } for(j=0;j<BIT_NUM_MAX;j++){ printf("%d",b); } printf("\n"); return b; } ``` Honored Contributor I

If I highlighted some error register. And print out the converted(decimal to binary) buffers, I got the value I wanted, but the problem is i want to save the value to bin_buffer since I will need them for further process.

My current objective is :

if dec_buffer = 1 ; bin_buffer ~ bin_buffer = 0 and bin_buffer = 1;

if dec_buffer = 2 ; bin_buffer ~ bin_buffer = 0 , bin_buffer = 1; bin_buffer = 0;

and soon..

Need some help here :) Thank you :D
