What is the main difference between for loop and while loop?
Here are few differences:
| For loop | While loop |
|---|---|
| Once the statement(s) is executed then after increment is done. | Increment can be done before or after the execution of the statement(s). |
| It is normally used when the number of iterations is known. | It is normally used when the number of iterations is unknown. |
Is there any difference between for loop and do while loop explain your opinion?
Unlike a while loop, a for statement consumes the initialization, condition and increment/decrement in one line thereby providing a shorter, easy to debug structure of looping….Here is the difference table:

When is the condition true in a while loop?
The condition is true if a non-zero value is returned and becomes false in case zero is returned. The loop repeats itself in case the condition becomes true. In case the condition becomes false, then the next line of the code, which is immediately after the iteration command, gets executed.
Why is the scope of a for loop limited?
Destruction of the variables inside the for loop body occurs before i is incremented. As for why; loops actually take a single statement for their body, it just happens that there’s a statement called a compound statement created by curly braces. The scope of variables created in any compound statement is limited to the compound statement itself.
How is initialization done in a while loop?
In while loop if initialization is done during condition checking, then initialization is done each time the loop iterate. In ‘for’ loop iteration statement is written at top, hence, executes only after all statements in loop are executed.
