Exam 3: Control Structures

All if statements must include an else header.

All relational operators produce a Boolean result (value).

Give an appropriate expression for each of the following: -To determine if the name 'Charles' appears in a list called names.

Evaluate the following Python expressions for the variable assignments given. -num1 > num2 and flag1

The following code is an example of

Which of the three forms of control flow is implicit in a program?

What are the three forms of control flow provided by programming languages?

Multiway selection in Python can be implemented as

Boolean literals True and False are considered Boolean expressions.

Control flow refers to

The elif header provides a convenient means of using a single if statement for multiway selection that can always be implemented instead by use of nested if statements.

"Control structure" is another name for a control statement.

Multiway selection in Python can be constructed either by the use of a single if statement (with the use of multiple headers), or by the construction of a set of __________ if statements.

The Boolean operators in Python are _____, _____, and _____.

Which form of control flow repeatedly executes a set of instructions?

Examine the following lines of code: While True: Print('Hello World!') This is an example of

Both the Boolean and _____________ operators evaluate to a Boolean result.

Most programs are straight-line programs.

A definite loop is a loop that always executes at least once, whereas an indefinite loop is a loop that may or not execute at all.

Fill in the table, evaluating the Boolean expressions for x and y with the given values. Some have already been filled in.
