boolean - Bool statement in a while loop c# -
for code, had goto start; statement repeat section until valid name entered, teacher not goto had change it.
currently got i'm not sure why not working. begin program wont start cuz later in code use input username , not recognize when use in bool statement. purpose of testing removed username line later on , program opens skips bool statement.
please me make work. thanks
bool namevalidation = true; while (namevalidation == false) { console.write("enter name: "); // asks name username = console.readline(); if (regex.ismatch(username, @"^[a-za-z- ]+$")) // validates input containts characters and/or spaces { namevalidation = true; } else // error message if input not valid { console.clear(); // clear screen console.writeline("please enter valid name."); namevalidation = false; } }
set nameavalidation = false
bool namevalidation = false; while (namevalidation == false) { console.write("enter name: "); // asks name username = console.readline(); if (regex.ismatch(username, @"^[a-za-z- ]+$")) // validates input containts characters and/or spaces { namevalidation = true; } else // error message if input not valid { console.clear(); // clear screen console.writeline("please enter valid name."); namevalidation = false; } }
