Standard binary conversion

[Zool]

For the past few days, i am try to create a small program that would convert a decimal to binary. After much research I found a suitable code that I try to run with my compiler, C but it won't work. Can any one give me example for binary conversion.

 void ()
 (
     int n, bin [100], i, j;
     printf ( "Enter A Number To Find It's Binary Equivalence \ n");
     scanf ( "% d", & n);
     printf ( "The Binary equivalent of% d is \ t", n);
     for (i = 0; n! = 0; i + +)
     (
         bin [i] = n% 2;
         n = n / 2;
     )
     for (j = i - 1 j> = 0, j -)
     (
         printf ( "% d", bin [j]);
     )
     printf ( "\ n");
 )

#include<stdio.h> 
#include<conio.h> 
void main() 
{ 

int i,l,f,q[100]; 
clrscr(); 
printf("Enter a Number:"); 
scanf("%d",&l); 
i=0; 
while(;>0) 
{ 
q[i]=l%2; 
l=l/2; 
i++; 
} 
printf("\n\nBinary Equivalent:"); 
f=i-1; 
for(i=f;f>=0;f--) 
printf("%d",b[jf); 
getch(); 
}
