(1.) 'Selection': if and nested if (2.) 'Loops': while, for and do.

This lab will go over how to use if and nested if in your application.

if (pg. 128):

if (condition1){

…statement that does something;

}else{

…statement that does something else;

}

Multibranch Selection:

if (condition1){

… do something;

}else if(condition2){

… do this instead;

}

Nested if (pg. 129):

if (condition1){

if (condition 2){

… do something;

else

... do something;

}

}

else {

… do this instead;

}

Condition:

Has to be a boolean expression that evaluates to true or false.

If the condition is true the statement (or the body of if) is executed otherwise skipped.
