The document discusses different types of iteration statements in C programming: 1. While loops repeat a block of code as long as a test condition is true. 2. Do-while loops are similar but check the condition at the end of the loop, so the body is always executed at least once. 3. For loops allow initialization of a counter variable, a test condition, and an increment/decrement expression to control the number of iterations. 4. The document also briefly mentions jump statements like continue, break, goto, and return which can alter normal program flow in loops.

- 1. Iteration Statements What you’ll learn: 1. while loop 2. do – while loop 3. for loop 4. Jump Statements
- 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
- 4. while loop Syntax: initialization; while (test_condition) { ...block of code... increment/decrement; } loop bodycondition True False exit from loop instructions
- 6. do – while loop Syntax: initialization; do { …block of code… increment/decrement; } while (test_condition); condition True Exit from loop Loop body False
- 8. for loop Exit from loopcondition False True Loop body initialization Syntax: for ( initialization; test_condition; update_expression ) { …block of code… } Update Expression
- 9. Jump Statements What are jumping statements ?
- 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
