FAQs on Do-while Loop in C++ Video Lecture - Crash Course for EmSAT Achieve
| 1. What is a do-while loop in C? |  |
Ans. A do-while loop is a control flow statement in the C programming language that allows a block of code to be executed repeatedly until a certain condition is met. It is similar to the while loop, but the difference is that the do-while loop executes the block of code at least once, even if the condition is initially false.
| 2. How does a do-while loop work in C? | |
Ans. The do-while loop first executes the block of code and then checks the condition. If the condition is true, the loop will continue to execute the code block repeatedly. If the condition is false, the loop will exit and the program will continue with the next line of code.
| 3. What is the advantage of using a do-while loop in C? | |
Ans. The advantage of using a do-while loop is that it ensures the block of code is executed at least once, regardless of the condition. This can be useful in situations where you want to prompt the user for input or perform an action before checking a condition.
| 4. Can the condition of a do-while loop be false from the beginning? | |
Ans. No, the condition of a do-while loop cannot be false from the beginning. Since the block of code is executed first and the condition is checked afterwards, the loop will always execute at least once before checking the condition.
| 5. How do you exit a do-while loop in C? | |
Ans. To exit a do-while loop in C, you can use the "break" statement. When the break statement is encountered within the loop, the control is transferred outside the loop and the program continues with the next line of code.
