C Program to check whether a Number is Binary or Not1 min read

In this tutorial, we will write a program to check for the binary number in C.

What is a Binary Number?

A binary number is a number expressed in the base-2 numeral system that is the number that contains 2 symbols to represent all the numbers. The symbols are 0 and 1.

For example: 101011, 110011110, 10001111 are binary numbers.


C Program to check whether a Number is Binary or Not

We have used the while loop to iterate through the entered number in the program below. The program takes the input of a number from the user.

With each iteration, there is an if condition to check for 1 and 0 in the digit, If it is not 1 or 0 then it is not a binary number.

Output:

Enter the Number: 1101
1101 is a binary number
