We can also make the sprite tell the answer by joining text and string.
For this, we need to use the following code for the sprite Abby. The output of the
code will be similar to this depending upon the input of the user.
LOOPS
All the programs or projects developed till now ran only once. If you want to run
a set of statements more than once, you will either run the code again or write
the script again. In Scratch, we can save our time and effort by repeating the code
without writing the program again or writing the script again. The automatic
running of a set of instructions more than once is called looping. The blocks for
looping are given in Control category.
repeat 10
The Repeat block is used to run a set of instructions for a specified
number of times.
The Repeat Until block is used to run a set of instructions till a repeat until
condition is satisfied.
The Forever block is used to run a set of instructions continuously forever
until stopped. The instructions inside this block will be executed in
a loop until the Stop button is clicked by the user.
The Repeat and Repeat Until blocks can be used to display the table of a number
input by the user. The script for the sprite can be like this (using Repeat Until block).
