LOOPS

The act of repeating an action again and again in called looping .

Let us understand loops with the help of an example.

You can observe that first Harry goes up

towards the sky.

In the second round, Harry and Jerry are both at the

same level.

In the third round, Jerry is at a higher level. Thus,
the cycle goes on.

Repeating a set of steps is a loop .

UNDERSTANDING PROGRAMS
A computer understands step-by-step instructions written only in a unique language,
called as program . The computer reads the program we write and follows as per our

instructions.

Let's write a program to make a square.

Move 2 steps right.

Move 2 steps up.

Move 2 steps left.
Move 2 steps down.
