Hi there! I am Studyfin, your friendly coding helper. Today we will learn how loops make coding fast and fun!
Sometimes we want to do the same task many times. In coding, we use a loop to repeat steps easily.
Imagine a robot that needs to take three steps. Instead of writing 'step' three times, we use a loop block to repeat it.
We can use loops to solve real problems. A loop saves time and keeps our code clean and short.
✏️ Worked example
Let us design a program to water four flowers in a row. How can we use a loop to do this?
- First, we look at the problem. We have four flowers to water.
- Next, we find the action that repeats. The action is: water one flower and move to the next.
- Then, we count how many times to repeat. We have four flowers, so we repeat four times.
- Finally, we write the loop. We put 'Water and Move' inside a 'Repeat 4 Times' block.
