How to Convert Number Decimal to Binary in C

Structure of the Problem Requirements 

A Simple C Program to Convert the Decimal into Binary equivalent Numbers. We have used a While loop, Modulus(%) and Division(/) operator . We have used an Array "ar" to store the Binary Output(remainder) for proper formatting of output.

Source Code

#include<stdio.h>

int main()

{

int a=0,b=0,n,i=1,j,k=0;

int ar[10]={0,0,0,0,0,0,0,0,0,0};

printf("\n \n ***************** CONVERT DECIMAL TO BINARY ****************");

printf("\n \n Enter Decimal Number : ");

scanf("%d",&n);

while(n!=0)

{

a=n%2;

b=n/2;

ar[i++]=a;

n=b;

k++;

}

printf(" \n \n BINARY NUMBER : ");

for(j=k+1;j>=1;j--)

{

printf("%d",ar[j]);

}

printf("\n \n ");

return 0;

}

Output of the Program
