In this video, we will write a C program to Check Whether an input number is Even or Odd.
Basically, if a number is divisible by 2 and gives a remainder 0 is known as an EVEN number. Apart from that, Odd numbers are numbers that are not divisible by 2 and give a remainder of 1.
Algorithm:
Step 1: Take input of a number from the user.
Step 2: Divide that number by 2.
Step 3: If the remainder is 1, then the number is odd.
Step 4: If the remainder is 0, then the number is Even.
Step 5: Print result and stop the program.
In the video, to check whether the number is even or odd we use two different methods:
1. Using if-else condition
2. Using Bitwise AND operator
Examples :
Input: n = 37
Output: Odd
Input: n = 160
Output: Even
Apart from that, we will see the time and space complexity of both the methods ,i.e
Time Complexity: O(1)
Space Complexity: (1)
