Chapter Profile
This variable “Fruit“ is a string variable as we are saving names in the variable. If you save
numbers in a variable, say 10, it will be a numeric variable.
CONDITIONAL BLOCKS
Many times, you have to do a task which is dependent on some condition. For example, you
have to make mango shake. There are two conditions:
a. Go to the refrigerator and check if there are mangoes. If mangoes are there, then you
will make mango shake.
b. If the mangoes are not there, you will make cold coffee.
Here the condition is the availability of mango.
We can also write this in two ways:
1. if 2. if
mango is available mango is available
then then
make the mango shake make the mango shake
else
make cold coffee
In such situations we use conditional blocks. Scratch has two conditional blocks. They
are:
1. If…then block: In this block if the condition is true, the blocks inside conditional block
will run. If the condition is false, the blocks inside conditional block will not run. Only the
blocks outside the conditional block will run.
2. If…then…..else block: In this block if the condition is true, the blocks inside then
condition will run. If the condition is false, the blocks inside else condition will run.
You can also use the forever and repeat blocks with these blocks.
