C code for decimal to binary conversion

#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;
