Chapter 4; Making Decisions

= vs ==

the first is a operator while the second is a assignment operator. The == operator determines whether a variable is equal to another value, the = operator assigns the value on the right to the value on the left

All relational operators are binary, which means that

they use two operands

How does a computer store what is true and what is false?

0 is false, all other are true 7

Relational Expressions are also known as..

Boolean expressions, which means that the value can only be true or false

Relational Operators Greater than Less than Greater than or equal to less than or equal to equal to not equal to

Relational Operators & what expression means x > y; Is x greater than y? x < y ; Is x less than y? x >= y ; Is x greater than or equal to y? x <= y ; Is x less than or equal to y? x == y ; Is x equal to y? x != y ; Is x not equal to why All relational operators have left to right associativity. Recall that associativity is the order in which an operator works with its operands

Relational Operators

Relational operators allow you to compare numeric and char values whether one is greater than, less than, equal to, or not equal to another

The if statement

The if statement can cause other statements to execute only under certain conditions

decision structure

a specificaction is taken when a spesific condition exsits

Sequence structure

a type of code in which the statements are executed in a sequence

x > y is called a

relational expression; it is used to determine whether x is less than y

z = x< y

relational expressions have a higher precedence than the assignment operator, worked out then assigned
