Chapter Profile
If you miss one step or do not write the steps in the correct order, the output will not be
what you want it to be.
The step-by-step procedure is also called algorithm.
DECISION MAKING
Ruhi is getting ready for school. She looks outside the window. It was raining.
Oh! It's raining.
What to do? If (it’s raining)
then
Carry an umbrella and go to
school.
otherwise
Don’t carry an umbrella.
This explains that when a condition like ‘if’ is given, there are two choices:
1. When the ‘If’ condition is a ‘Yes’, then we follow ‘then’ statement.
2. When the ‘If’ condition is a ‘No’, then we follow ‘otherwise’ statement.
Decision making is a process of arriving at a conclusion by making a choice.
LOOPS
The act of repeating an action again and again is 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.
