C Loops and switch statements

ripwheels8 · 11-13-2004, 01:33 PM

I am trying to write a program using a switch statment in a loop until a certain variable is entered. What command do I use and how do I place the switch inside the loop? Your assistance is greatly appreciated. Thank you.

You could have a variable that is set when the value you want to use to the exit the loop is set, and then check for it at the top of the loop (breaking if it is set). The ugly and unrecommended way to do it, is to use a goto from within the switch statement itself, in the case you want to cause to exit the loop.

You could do it of many ways.
The way you refer to:

Code:

for(;;)
 switch{
  case '0':
    ...
  case '1':

}

I had a problem posting the last thread.

What ripwheels8 refers to:

Code:

for(;;) /* Endless Loop */
 switch(x){
  default:
    ...
   case 0:
    ...
   case 1:
    ...
/* And so forth */
 }

I think btmiller refers to:

Code:

for(x = VALUE; x != SET; ...){
  ...
}

well, think about how you would do this:

assign a variable inside your program.
you would look between the curly braces of main, right? RIGHT!

so if you want to nest something in side a loop, just place it within the curly braces. Don't get confused about what braces match! You can also nest as many things as you wish, NO limit
