Whole Number:
A whole number is any positive number or zero without any fraction or decimal part. Unlike integers, whole numbers include only the positive numbers starting from 0. For example, 0, 1, 2, 3, 4, 5 are all whole numbers.
Counting Number:
Counting numbers, also known as natural numbers, are the positive integers used for counting or ordering objects. Counting numbers start from 1 and continue indefinitely without any decimal or fraction part. For example, 1, 2, 3, 4, 5 are all counting numbers.
