Yes. If the software license restricts use to a single computer or a single user, its still piracy, even though you split the cost

A Program written in a high-level programming language.
Expression
an arrangement of identifiers, literals, and operators that can be evaluated.

The condition that causes the loop to exit]
valid or invalid: elizabeth_the_2nd
valid
Strategy: Means-ends analysis
Look at the input, output, and available operations and find a sequence of operations that transform the input into the output.
Section 2
(50 cards)
Can we concatenate endl with a string in an expression? Explain.
No. the endl identifier is a manipulator, and is not a string value.
The "equals or greater" operator in C++ is written =>. True or False?
false. >=
Which c++ construct do we use to implement modules?
pseudocode
The bool operators have lower precedence than the arithmetic operators, with the exception of the ! operator, which has the same precedence as unary minus. True or False?
true
1st step in the problem-solving phase of the software life cycle: Analysis and specifications
understand (define) the problem and what the solution must do
List the three steps in the problem-solving phase of the software life cycle

What is the result if the computer tries to calculate a value that is larger than the maximum integer allowed for a given integral type?
integer overflow
Is MAIN a value-returning function or a void function?
void function
What is wrong with each of the following statements? cout >> maximum
cout << maximum
What are the two meanings of the / operator?
division for floating-point and integer
Define the term "flow of control."
The order in which the computer executes statements in a program
Void function
A function that is called as a separate statement
