Demonstrate a do-while loop program that asks the user to enter two numbers. The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate.

Write a loop that asks the user “Do you want to repeat the program or quit? (R/Q)”. The loop should repeat until the user has entered an R or Q (either uppercase or lowercase).

How many times will the following do-while loop be executed? int x = 0; do {      System.out.println(”looping through…”);      x += 25;    } while (x > 50);   a) 0   b) 1   c) 2   d) 3

If you are writing a while loop that increases the counter variable i by 1, and want the loop to stop after six iterations, you should _____. a. initialize i with a value of 1 and use i <= 5 as the conditional expression b. initializeiwith a value of 0 and usei <= 5as the conditional expression c. initialize i with a value of 1 and use i >= 1 as the conditional expression d. initializeiwith a value of 0 and usei < 7as the conditional expression
