2. What are iteration statements?
 An iteration statement, or loop, is a way
of repeating a statement, known as loop
body, a number of times until some
condition is satisfied.
 We have following types of iteration
statements in C:
 while loop
 do-while loop
 for loop
Set of
instructions
condition
True
False

10. What are jumping statements?
 Jump statements can be used to modify the behavior of conditional and iterative
statements.
 Some jump statements provided by C are:
o continue
o break
o goto
o return
