Computer Science A Unit 3

will only run and execute when a certain condition is true; and will ignore the code if the statement isn’t true

one-way selection

The order in which different lines of code will run

Typically each line of code runs from top to bottom

If statements can change the sequence

if -else statement, meaning there are 2 watts that the code could run, the if or the else

If-else-if statement, which only runs one of the man y different listed conditions

logical operations that check for multiple conditions at once

combines 2 separate Boolean expressions into a single compound Boolean expression

statement or condition that evaluates to true of false

used to look at all possible values of the variables, and determine the value of the whole statement

When the result of a logical expression using && or || can be determined by evaluating only the first Boolean expression, the second is not evaluated

If both A and B are true, them the whole expression is true

If some part of a || statement is true, then the whole expression is true
