Step 6 Your hot chocolate is ready. Enjoy!

Selection

In selection, the algorithm comes to a point where it needs to ask a question. The

answer (YES or NO), decides which path it will follow next. Different answers lead to
different steps, helping the algorithm make smart choices.

For example, deciding what to wear today.

Algorithm:

Step 1 Start

Step 2 Wake up and look outside the window.

Step 3 Check if it is cold today.

If YES, wear a warm sweater and trousers.

If NO, wear a light t-shirt and shorts.
Step 4 Put on your chosen clothes.

Step 5 Check yourself in the mirror.
If YES, you are happy with your look →

Move to Step 6.

If NO, you are not happy → Go back to
Step 3 and choose again.

Step 6 You are dressed and ready for the day.

Step 7 End

Repetition

In repetition, some steps are repeated again and again. The algorithm keeps doing

the same step until a certain condition becomes true and then moves forward. This
helps us avoid writing the same steps many times.

For example, practising multiplication tables.

Algorithm:

Step 1 Start

Step 2 Choose a number (for example, 5).

Step 3 Set a counter to 1.
