Write a program to print binary equivalent of given integer value in c?

Answer 1

Inorder to display a binary value of a number in C language, 1st create an integer array of size n. Then inside a for loop divide that number by 2 repeatedly and store the remainder in that array from 0 to n. The remainder is always a 0 or 1. Finally when the number itself reaches 1, put this 1 also in your array. Then display it by printing the array from n-1 to 0.

Answer 2

#include<stdio.h>

#include<conio.h>

void main()

{

int temp=0, num, mul=1, sum=0;

clrscr();

printf("enter the no:");

scanf("%ld" , &num);

while(num>0)

{

temp=num%2;

temp=mul * temp;

sum += temp;

mul *=10;

num /=2;

}

printf("%d", sum);

getch();

}
