can it be done without use of a goto? remember that the user can use
backspace to remove the previous entered string...eg...before pressing
enter, the user enters abc<bs>def so the string is abdef


How to decide how much buffer is optimum and would use of realloc be a good
strategy?

Also, i have a very basic question? Why GOTO is not recommended, i see it
used like anything in linux kernel..not able to corelate security
limitations in user mode vers kernel mode.
