breaking out of a do while loop with a switch nested inside.

MasterHex (4)
This is a small portion of the code i am working on. I am try to figure how i can exit this loop when asked to do so. But i have to allow the user to make multiple changes until the user tells the program to exit. i have every thing else figured out in the program but one part.

this is also inside an if statement.

do {
    switch(...) {
     //....
    }
    if(some_condition) break;
}while(true);

i have a .dat file that i am getting the information from. their are some calculations left out that i will be incorporating. I have compiled the program and it shows no errors, but for some reason it just keeps asking the quest no matter how many times i enter 'e' for exit. What i need to do is exit the do loop the and continue one with the program. I know the outdata portion is not right i will deal with after i get this problem resolved.
