if-else Operatorif-else Operator

if-else

The if-else statement is a staple in programming. It enables you to direct the flow of your program based on certain conditions.

Note

Just a heads-up! Code blocks { } were introduced in Section 1, Chapter 2.

The if-else structure is pretty straightforward:

Take, for instance, the temperature variable that receives data from a temperature sensor.

Suppose we want a program that alerts us when the temperature gets too high:

c

Main.c

You can incorporate multiple if statements in a program, especially when you need to evaluate various conditions.

Note

Conditions can also include logical operators.

Else If

The if-else statement can be further expanded with else-if:

c

Main.c

Note

AI stands for Artificial Intelligence.
