Study Notes
do...while Repetition Statement
- The do...while statement is similar in function to the while statement
- The loop condition is evaluated after the loop body has executed
- Therefore the loop body always executes at least once
- The do...while loop is often used when the loop body must execute at least once, even if the loop condition is not met on the first iteration
- In the example code provided
counteris initialized with the value 1 - In the do...while loop the code prints the value of
counterthen increments it by 1 (++counter) - The loop will continue to execute as long as the value of
counteris less than 10 - The code will print out the values 1 through 10
