It looks like this, but be careful, you have to reverse the resulting string :-)

#include 
#include 
#include 
char output[256]="";

int main()
{
int x= 192;
int n;
n = x;
int r;
do {
r = n % 2;
if (r == 1)
   strcat(output,"1");
else strcat(output,"0");
n = n / 2;
}
while (n > 0);

printf("%s\n",output);
}
