To convert a **decimal number** to a **binary number**

### Program:

#include<stdio.h> #include<conio.h> void main() { long b[20], n, r, c = 0, i ; clrscr() ; printf("Enter a decimal number : ") ; scanf("%ld", &n) ; while(n > 0) { r = n % 2 ; b[c] = r ; n = n / 2 ; c++; } printf("\nThe binary equivalent is : "); for(i = c - 1 ; i >= 0 ; i--) printf("%ld", b[i]) ; getch() ; }

### Output:

Enter a decimal number : 12 The binary equivalent is : 1100
