Program Help Login and Asterisk

deleon123 (11)
Please guys help me with this, disregard the bottom part, what I just need to take care of right now is the log-in process, the password should be in asterisk and the limit of login attempts should only be three. I can't seem to make it work like when you get the password correct it transfers you to the menu.

Input password 3 times, and the password appears to be all asterisks whatever the user inputs it?

So I wish you luck. This topic is for advanced C++ programmers only. I might want to do it but implementing such thing is time-consuming.

The program runs the password in asterisk characters it is already solved. But the main problem here is even if the password is wrong it still goes inside the menu.

Also the trials are fixed.

Your code does not look good and please get rid of goto. Code indentation is also important.
