Cs161 Chapter 4

Front 1

(____) operators are important for making decisions. They allow us compare numeric and char (chars are treated like numbers in C++) values to determine if one is greater than, less than, equal to, or not equal to another.

Back 1

relational

Front 2

Relational operators are (____) meaning they require two operands.

Back 2

binary

Front 3

Left to right (____) means that when two operators of same precedence are adjacent, the left most operator is evaluated first.

Back 3

associativity

Front 4

The integer values of the characters ‘a’ to ‘z’ range from (____) to (____)

Back 4

97, 122

Front 5

The integer values for ‘A’ to ‘Z’ range from (____) to (____)

Back 5

65, 90

Front 6

When a relational operator is used with (____), the integer value of each character of the left operand is compared to the integer value of each character of the right operand working from left to right.

Back 6

strings

Front 7

If you include the (____) header file in your program, you can access character testing functions

Back 7

cctype

Front 8

(____) variables are commonly named with an “is” prefix (such as isCold = true), but other common prefixes are "has", "should", and "can"

Back 8

flag

Front 9

Use an if/else statement if the two conditions are (____ ____) meaning if one condition is true the other condition must be false.

Back 9

mutually exclusive

Front 10

You can add a (____) else statement to the if/else if statement if you want to execute code if none of the if statements are true.

Back 10

trailing

Front 11

Use (____) operators to combine two or more relational expressions into one or to reverse the logic of an expression.

Back 11

logical

Front 12

The (_) operator performs a logical NOT operation.

Back 12

!

Front 13

When you combine multiple relational expressions by using the && or || operator, the expressions are evaluated left to right. As soon as the program can determine the result of the combined logical expression, it proceeds without evaluating any remaining sub-relational expressions, a process called (___ ___) evaluation.

Back 13

short ciruit

Front 14

For the logical OR operator, if the first expression is true, the second expression is not even tested. This process is called (____ ____) evaluation.

Back 14

short circuit

Front 15

For the logical AND operator, if the first expression is false, the second expression is not even tested. This process is called (____ ____) evaluation.

Back 15

short circuit

Front 16

A (____) of code is defined a set of statements enclosed within { and }.

Back 16

block

Front 17

The (____) operator provides an alternative way to implement if/else functionality.

Back 17

conditional or ternary

Front 18

Test expression ? expression for true: expression for false;

This is the syntax for the (____) operator.

Back 18

conditional or ternary

Front 19

The (____) statement provides functionality like that of the if/else if statement.

Back 19

switch

Front 20

For enum syntax, the integer assignment starts at the number (_)

Back 20

0

Front 21

enums are often declared (outside or inside) of main. This is because you often want to use your programmer defined data type throughout your whole program versus just a small block of code.

Back 21

outside
