Method to calculate Decimal to Binary Number

Take a decimal input from the user

for example :

if user enter a decimal 12

We keep on dividing the number 12 by 2.

12 / 2 = 6, reminder 0

06 / 2 = 3, reminder 0

03 / 2 = 1, reminder 1.

01/ 2 = 1, reminder 1.

Decimal to binary

So Binary equivalent of 12 is 1100.

Write all reminders bottom to top. It’s binary equivalent of decimal (12)10=(1100)02

Source Code :

#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int t, n, r=0, p=1, bin=0;
printf("Enter a number\n");
scanf("%d",&n);
t=n;
while(n>0)
{
    r=n%2;
    n=n/2;
    bin=bin+(r*p);
    p=p*10;
}
printf("Binary of decimal %d = %d",t,bin);
getch();
}
