Task 7: Now make the menu of the previous program stay on the screen until the user asks to
exit using an infinite loop. For that simply enclose the whole code in while(1) loop, as shown
in one of the practice tasks above and add a case 6: for exiting.
Hint: Enclose its code in the following while block, Except the declaration and
initialization statements.
while (1)
{
system(“cls”);
//adjust that code here, and add a 6 th case as shown below
case 6:
