Question

I want to know if there is a function in C library that convert a decimal to binary number and save number by number in a position on an array.
For example: 2 -> 10 -> array [0] = 0 array[1] = 1.
Thanks.

Answer 1

here:

void dec2bin(int c)
{
   int i = 0;
   for(i = 31; i >= 0; i--){
     if((c & (1 << i)) != 0){
       printf("1");
     }else{
       printf("0");
     } 
   }
}

But this only prints the value of an integer in binary format. All data is represented in binary format internally anyway.
