Is do-while loop executed only if the condition is true?
First the body is executed, then the condition gets checked.
Why are the statements in the body of a loop called conditionally executed statements?
These statements are called conditionally executed statements because the may or may not be executed. They will be executed while the boolean (true/false) statement in the beginning of the loop is true, but will not be executed when statement is false.
What is difference between for loop and do-while loop?
The do loop is similar to the forloop, except that the expression is not evaluated until after the do loop's code is executed. Therefore the code in a do loop is guaranteed to execute at least once. The following shows a do loop in action: do { System.out.println("Inside do while loop"); } while(false); The System.out.println() statement will print once, even though the expression evaluates to false. Remember, the do loop will always run the code in the loop body at least once. Be sure to note the use of the semicolon at the end of the while expression.
When would you use a count controlled loop vs. a flag controlled loop?
Counter Loop:Counter loop is a loop which executes statement up to a fixed number of time.In GW FOR ... NEXT loop is used as counter loop.Controlled Loop:Controlled loop is used to extend the statements till a specific condition is satisfied. In GW WHILE ... WEND is used as controlled loop.
What are the components of loop?
a loop consist of data initialization;test condition;updation; example a for loop for(int a=1;a<5;a++) the loop will be executed 5 times four positives result and the last test condition will be failed and the loop will be exited there are many loops some of them are while loop,do...while loop,for loop,maybe more...... do while is an exit check loop and while and for are entry check loop.
