#include<stdio.h>  
int main(){ 
    long int decimalNumber,remainder,quotient;
     int binaryNumber[100],i=1,j;  
     printf("Enter any decimal number: ");  
     scanf("%ld",&decimalNumber);  
    quotient = decimalNumber;  
    while(quotient!=0){ 
         binaryNumber[i++]= quotient % 2;     
         quotient = quotient / 2;
     }  
    printf("Equivalent binary value of decimal number %d: ",decimalNumber);  
   for(j = i -1 ;j> 0;j--)     
     printf("%d",binaryNumber[j]);  
    return 0;
