Control Flow
The If-then Statement
It tells your program to execute a certain section of code
only if a particular test evaluates to true.
void stopCar() {
// the "if" clause: car must be stopped
if (isMoving) {
// the "then" clause must stop car
isMoving = false;
}
}
Control Flow
The If-then Statement
The opening and closing braces are optional, provided
that the "then" clause contains only one statement:
void stopCar() {
// same as above, but without braces
if (isMoving)
isMoving = false;
}
