>how to convert decimal to binary using c library
I assume you mean "how do you print a number in binary"?
Well in the spirit of not doing too much of others' homework...
$ type test.c
#include <stdio.h>
#define Show(a) printf("\n" #a " = 0b");pb(a);
void pb(unsigned long ul)??<
if (ul>1)??<
pb(ul>>1);
printf("%d", ul%2?1:0);
??>else
printf("%d", ul?1:0);
??>
int main(void)??<
Show(0);
Show(1);
Show(16);
Show(15);
Show(32767);
Show(0777);
Show(0xDeadBeef);
return 0;
??>
$ testc
0 = 0b0
1 = 0b1
16 = 0b10000
15 = 0b1111
32767 = 0b111111111111111
0777 = 0b111111111
0xDeadBeef = 0b11011110101011011011111011101111
