IT IS THE LITTLE THINGS THAT MAKE A BIG DIFFERENCE

IT IS THE LITTLE THINGS THAT MAKE A BIG DIFFERENCE

There was a man taking a morning walk at or the beach. He saw that along with the morning tide came hundreds of starfish and when the tide receded, they were left behind and with the morning sun rays, they would die. The tide was fresh and the starfish were alive. The man took a few steps, picked one and threw it into the water. He did that repeatedly. Right behind him there was another person who couldn't understand what this man was doing. He caught up with him and asked, "What are you doing? There are hundreds of starfish. How many can you help? What difference does it make?" This man did not reply, took two more steps, picked up another one, threw it into the water, and said, "It makes a difference to this one."

What difference are we making? Big or small, it does not matter. If everyone made a small difference, we'd end up with a big difference, wouldn't we?

/* C program to find LCM of two positive integers entered by user */

Output:
Enter two positive numbers: 15 9 
LCM of two numbers 15 and 9 is 45

Output 1:
Enter year: 2000 
2000 is a leap year.
Output 2:
Enter year: 1900
1900 is not a leap year.
