If Expression

To perform different actions depending on the different decisions we can use already mentioned logical operators and the conditional statement if.

if executes the block of code if the condition is true. In C++, it's implemented as follows:

For example, we know how to check if the variable x is greater than y. Let’s write the message (with the statemant if) if this condition is true (x is bigger than y):

As x is 7, and y is 5, x is greater than y, so our condition is true and the code will print the message "x is bigger than y".

The statement if is case sensitive. It means that usage of uppercase letters (If or IF) will cause an error.
