Then we will also learn about creating a program that will print all the even and odd numbers from start to the number given by user.

That is if the given number is divisible by 2, then it will be an even number and if the number is not divisible by 2, then it will be an odd number. As the above program was written and run under Code::Blocks IDE, therefore after successful build and run, you will get the following output. This is the first snapshot of the sample run:.

Now supply any number say 13 and press ENTER key to see the output as shown here in the second snapshot of the sample run:.

Here is another program that will ask from user to enter the value of N. And then print all the even numbers from starting to N. Let's suppose that if user has supplied 20 as the value of N as input, then all the even numbers will be printed between 1 to 20 including both. This time the following program will ask from the user to enter the value of N to print all the odd numbers exists in between 1 to N including both. Here is the program:. Tools Calculator. All Rights Reserved.When the number is divided by 2 and the balance becomes zero and the above number is called as the even number — eg 2,4,6,8, Once this program received the number it will check the given number either odd or even number of given range using loops.

After receiving the input from the user, it is stored in the variable of num and then program divides the value of num by 2 and displays the output. For loop in C language. While loop in C language.

C Program to Print the Number of Odd and Even Numbers in an Array

Thx but I wanted to keep the closest code as the OP post I edited my answer. You probably should at least write out something when the user enters a non-integer value that isn't "exit".To determine if a given integer is odd or even we should check its least significant bit LSB. If least significant bit of an integer is 1, it will be an odd number else it would be even.

When bitwise AND is performed on an integer and 1 then result will be 1 if the integer is odd, else the result will be zero. Following program develops a small C function isOdd that receives an integer as input and return zero or one depending upon the inputted number is even or odd. Hope you have enjoyed reading C program that checks if a given integer is odd or even using bitwise operators.

It divides the input number be 2 and if remainder is 0 then it returns 0 even number otherwise 1 odd number. If the least significant bit of number is 0, then number is even otherwise number is odd.
