C++ Chapter 05

True/False: The condition that is tested by a while loop must be enclosed in parentheses and terminated with a semicolon.

False

True/False: The scope of a variable declared in a for loop's initialization expression always extends beyond the body of the loop.

False

True/False: A while loop's body can contain multiple statements, as long as they are enclosed in braces.

True

The statements in the body of a while loop may never be executed, whereas the statements in the body of a do-while loop will be executed: at least once at least twice as many times as the user wishes never None of these

at least once

This statement causes a loop to terminate early. stop break null terminate None of these

break

This statement may be used to stop a loop's current iteration and begin the next one. break terminate re-iterate continue None of these

continue

The do-while loop is a(n) ________ loop that is ideal in situations where you always want the loop to iterate at least once. post-test pre-test infinite null-terminated None of these

post-test

The do-while loop is considered a(n) ________ loop. pre-test post-test infinite limited None of these

post-test

The while loop is this type of loop. post-test pre-test infinite limited None of these

pre-test

This operator increments the value of its operand, then uses the value in context. prefix increment postfix increment prefix decrement postfix decrement None of these

prefix increment

This is a special value that marks the end of a list of values. constant variable loop sentinel None of these

sentinel

This is a control structure that causes a statement or group of statements to repeat. decision statement constant loop cout object None of these

loop

This is a pre-test loop that is ideal in situations where you do not want the loop to iterate if the condition is false from the beginning. do-while while for infinite None of these

while

The while loop has two important parts: an expression that is tested for a true or false value, and: a statement or block that is repeated as long as the expression is true a statement or block that is repeated only if the expression is false one line of code that is repeated once, if the expression is true a statement or block that is repeated once, if the expression is true

a statement or block that is repeated as long as the expression is true

True/False: The increment and decrement operators can be used in mathematical expressions; however, they cannot be used in relational expressions.

False

True/False: If you want to stop a loop before it goes through all its iterations, the break statement may be used.

True

This loop is a good choice when you know how many times you want the loop to iterate in advance of entering the loop. do-while while for infinite None of these

for

This means to increase a value by one. decrement increment modulus parse None of these

increment

The while loop contains an expression that is tested for a true or false value, and a statement or block that is repeated as long as the expression: is false is true does not evaluate to true or false evaluates to true or false None of these

is true
