How to print all even number in c programming (logic)

Print all even numbers in c programming

To print all even numbers from a range in c programming, we have to check all numbers between the given range. To check if the number is odd or even number, we can use the following logic:

If any number is fully divided by 2, then this number is even. Else the number is odd. 
Even and Odd

For example

If we want to check whether the number 5 is odd or even, we need to simply divide the number by 2.
If there is any remainder left or any value of 5 mod 2 left, that means 5 is not divisible by 2. So 5 is an odd number.


So the algorithm becomes.

if(number % 2 == 0){
                  number is even;
else if(number % 2 != 0){
                  number is odd;
[Note: here "%" sign is to calculate mod or remainder of division]

I hope the logical part of "How to print all even numbers in c programming" is clear now. So now time to implement this in c programming. Again now you can "print all odd numbers in c programming."
Don't see the code now. At first, try it yourself and then go to see the code in c programming to print all even numbers.

Now time to practice the following:

  1. But 30 ÷ 2 = 15 leaving no remainder 15 is odd

    1. Here you are checking 30 whether 30 is odd or even. As 30 mod 2 = 0, 30 is even.
      In case of 15, 15 mod 2 != 0, so 15 is odd...

  2. Programming is combination of intelligent and creative work. Programmers can do anything with code. The entire Programming tutorials that you mention here on this blog are awesome. Beginners Heap also provides latest tutorials of Programming from beginning to advance level.
