Ans:
In this tutorial you will learn how to write a program in C programming language to check a given number representation is in binary or not.
Here we are not going to check any base of number.
As you know we can represent any number in binary format like in 0 and 1.
Just like the binary representation of 2 is 0010.
So we will check only if given input number has 0 and 1 or is any other digits.
In the below program if someone give any input in 0 and 1 format then our program will run and give output as given number is in binary format.
And if someone give another number different from 0 and 1 like 2, 3 or any other then our program will give output as given number is not in a binary format.
Below is the C program to check given number representation is in binary or not
#include<stdio.h>
#include<conio.h>
int main() {
int j,num;
printf("Please enter a number :");
scanf("%d",&num);
while(num>0)
{
j=num%10;
if( j!=0 && j!=1 )
{
printf("num is not binary");
break;
}
num=num/10;
if(num==0)
{
printf("num is binary");
}
}
getch();
} Output:
Explanation of the above program
- This is very simple program to check the given input is in binary form or not.
- In the above program our logic is just to check the each digit of the given input.
- If any digit is different from 0 and 1 then program will print “num is not binary”.
- Otherwise it will print “num is binary”.
I hope you understood it.
