What is the purpose of the if statement?

The ability to control the flow of your program, letting it make decisions on what code to execute, is valuable to the programmer.

How to have more than one statement execute after an if statement?

To have more than one statement execute after an if statement that evaluates to true, use braces, like we did with the body of the main function. Anything inside braces is called a compound statement, or a block. When using if statements, the code that depends on the if statement is called the "body" of the if statement. For example:

What happens if the else statement is true?
