Question
Which C++ loop is best suited for situations where the number of iterations is not known in advance and the loop should continue as long as a certain condition is met?Select one:a. do-while loopb. switch loopc. for loopd. while loop
Solution
The best suited loop for situations where the number of iterations is not known in advance and the loop should continue as long as a certain condition is met is the while loop (option d).
Here's why:
a. do-while loop: This loop will execute the block of code once before checking the condition. Then it will repeat the loop as long as the condition is true. It's not the best choice when you don't know the number of iterations and you want to check the condition before executing the loop.
b. switch loop: There's no such thing as a switch loop in C++. The switch is a control statement that allows a variable to be tested for equality against a list of values.
c. for loop: This loop is used when you know the exact number of times a block of code needs to be executed.
d. while loop: This loop will continue executing the block of code as long as the condition remains true. It's the best choice when you don't know the number of iterations in advance.
