Hackerrank Day 3 Intro to Conditional Statements Solution in C, C++, and Java programming language. In this programming problem, we are going to learn about the If-Else statements, We have to use Even-Odd logic, and Greater and Less Number logic to solve this Programming Problem of Hackerrank Website.

Problem Statement:- According to the Hackerrank, you should follow these four given conditions. Hackerrank Intro to Conditional Statements Solution in C.

  • If ‘n‘ is odd, print Weird.
  • If ‘n‘ is even and in the inclusive range of 2 to 5, print Not Weird.
  • n‘ is even and in the inclusive range of 6 to 20, print Weird.
  • If ‘n‘ is even and greater than 20, print Not Weird.

Intro to Conditional Statements Solution Explained

Let’s start, so we have a number n and we need to write a program that follows the above four condition as we can see that our first condition is if n is odd that program will print number “Weird“.

So for this first condition, we divide a number by 2 if a number is divisible by 2 then number is even and if number is not divisible by 2 then it will print number is “Weird‘.

Now come to the second condition if the number is even and range of 2 to 5 the program will print number “Not Weird“, for that again each number we divide by 2 if number is even and number is between range(2 to 5) the program will print Number is “Not Weird“.

Again comes to the third condition if the number is between 6 to 20 then program will print number is ” Weird“. same as the second condition. Again check for the fourth condition if the number is greater than 20 then the program will print number is “Weird“.
