Compare and contrast the while and for iteration statements.

Question

What will be an ideal response?

Answer 1

The while and for iteration statements repeatedly execute a statement or set of state-
ments as long as a loop-continuation condition remains true. Both statements exe- cute their bodies zero or more times. The for statement specifies the counter- controlled-repetition details in its header, whereas the control variable in a while statement normally is initialized before the loop and incremented in the loop's body. Typically, for statements are used for counter-controlled repetition, and while state- ments are used for sentinel-controlled iteration. However, while and for can each be used for either iteration type.
