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.
You can also write this in two ways:
1. if 2. if
mango is available mango is available
then then
