Hey guys below is my full code of the program I am trying to run. I want to save the data automatically. It goes through many areas but the save area is not working for some reason. Errr...I have spent many hours and it is very basic code probably because I use a while statement instead of a cin or cout statement. If you can help that is awesome! I am a beginner and doing this for school have the dietzel book which is crap.

This program grabs employee information for a business and saves the file. It then can create employees and further more. I tryed keeping it very organized to easily read!

Thanks All!

p.s. I had a file made as "a" in my C:// file, but had to change it to a .txt file to save the information. Please not that a file has to be saved in the C:// file to search for the information or folder. The folder has lines of numbers to simulate the information.

just to start, i notice a couple things:

warning: return type of ‘main’ is not ‘int’

"void main" is wrong. don't do it.

warning: the `gets' function is dangerous and should not be used.

NEVER EVER USE GETS.

ever.

fix those things and we can move along.

this program, i hate to tell you, has a number of problems. for instance, i cant even get past the "getInput" function. what is going on here?

while (userName[nameLenght] != 0){
		nameLenght++;
	}

	for(i = nameLenght; i > 0; i=i-1);{

		printf("username = %s\ni = %d\n\n\n\n",userName,nameLenght);


		userName[i + 3] = userName[i];
	} // end For loop

i'm not sure what you're trying to do, but the result is mangling the userName string. do you notice that you're writing BEYOND the end of the string!

another major problem I personally have, is that you are hardcoding the C:\ directory as the place to read and write?? i dont have a C:\ directory. you're assuming we all use windows... well, we don't. and even if i decided to go get on a windows machine, like my wife's laptop, the last thing I would want to do is let your program write to the root drive.

that is really a bad idea, generally speaking. you should instead read and write to a relative drive location determined by the working directory in which you execute the program.

as it stands right now there's little i can do to help you since I'll never be able to get this working on my machine without a significant rewrite.
