problem again

Expand Post »

hello ppl
this is my 2nd post and as i said earlier, im writing a cpp program for an exam project.
the project is designing a school database system

neways the problem is that the the compiler hangs and terminates whenever a wrong type of data is entered i mean if (ch is an integer and text is entered)
chk out the code below for example. its a snippet of the whole prog but ive edited it so tht it can run independently for testing.

i have tried many things to stop this from happening like clearing the values of the variables every time a wrong input is given but... it dosent work
and also if there are places where something simpler could have been done please tell me

PLEASE HELP

thanx in advance

Re: problem again

Simple. Always get stuff from the user as a string. Then check it and get from it what you need. If you don't find it - shoot an error and let a new input be given. There are some lines of code that you pasted there.. it's quite long for somebody to look through it and simplify it. After some time, when you become a better programmer go through the program yourself and make it better!
