 Problem Name: 30 days of code - Day 3: Intro to Conditional Statements

Problem Link: https://www.hackerrank.com/challenges/30-conditional-statements/problem?isFullScreen=true

In this HackerRank in 30 Days of Code - Day 3: Intro to Conditional Statements problem solution,

Objective
In this challenge, we learn about conditional statements. Check out the Tutorial tab for learning materials and an instructional video.

Task:

Given an integer,perform the following conditional actions:

  • If n is odd, print Weird
  • If n is even and in the inclusive range of 2 to 5, print Not Weird
  • If 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

Input Format:

A single line containing a positive integer, n.

Constraints:

1 < n < 100

Output Format:

Print Weird if the number is weird; otherwise, print Not Weird.

Sample Input 0:

3

Sample Output 0:

Weird

Sample Input 1:

24

Sample Output 1:

Not Weird

Explanation:

Sample Case 0: n = 3

n is odd and odd numbers are weird, so we print Weird.

Sample Case 1: n = 24

n > 20 and n is even, so it is not weird. Thus, we print Not Weird.

// If  is even and in the inclusive range of  to , print Not Weird
// If  is even and in the inclusive range of  to , print Weird
// If  is even and greater than , print Not Weird

int main()
{
    int n;
    scanf("%d",&n);

    if(n%2==1 || (n%2==0 && n>=6 && n<=20))
    printf("Weird\n");
    else if(n%2==0 && ( (n>=2 && n<=5) || n>20))
