Convert decimal number to binary in C -

for assignment need convert 16-bit decimal number binary number. example number 9 should print 0000000000001001. professor started code:

void printbinary(short n) { }  int main(int argc, char **argv) {     short n;     printf("enter number: ");     scanf("%hd", &n);     printbinary(n); } 

i confused go here. appreciate helping me understand do, new coding. in advance.

try this:

int printbinary(int integer) {   int remainder, counter = 0, my_binary = 0; while (integer > 0) {     remainder = integer % 2;     my_binary += remainder * pow(10, counter);     integer /= 2;     counter++; }      printf ("binary %d\n", my_integer"); } 

this has been taken here.

note: have assumption want convert positive decimals.
