Chapter 5: Problem 56

True or False Variables may be defined inside the body of a loop.

Short Answer

Expert verified
True In most programming languages, variables can be defined inside the body of a loop. The scope of the variable in this case will be limited to the loop body, and it will be created and destroyed with each iteration of the loop. This can be useful when a variable is only needed for a specific computation within the loop and does not need to be maintained across iterations or outside the loop.

Which loop should you use when you know the number of required iterations?

Write a do-while loop that asks the user to enter two numbers. The numbers should be added and the sum displayed. The user should be asked if he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate.

Which loop should you use in situations where you wish the loop to repeat until the test expression is false, and the loop should not execute if the test expression is false to begin with?

\(\mathrm{A}(\mathrm{n})\) ______________ is a variable that is initialized to some starting value, usually zero, and then has numbers added to it in each iteration of a loop.
