    ok i put the function prototypes outside! and it seem to be running properly for 2 sets of data ONLY :/ not more!
    Code:
    int main()
    {
        Individual I[1];
        menu(I);       
    }
    
    Can you see why you can't put more than two instances of Individual into the array named "I"?

    Gah! The program is full of hidden Windows characters that I'm having trouble getting rid of. Anyone having more success?

    hey i did as you asked and it seems to be working!...btw what type of compiler do you recommend jweoblewski44?
    Code:
    #include <stdio.h>
    
    typedef struct{
            char name[50];
            int age;
            char gender[50];
            int position;
            }ind; //Individual
            
    void input(ind I[], int n);
    void output(ind I[], int n);
    
    void input(ind I[], int n)
    {
         int x;
         for(x=0; x<n; x++)
         {
                  printf("Enter name: ");
                  scanf("%s", I[x].name);
                  printf("Enter age: ");
                  scanf("%d", &I[x].age);
                  printf("Enter gender: ");
                  scanf("%s", I[x].gender);
                  printf("Enter position: ");
                  scanf("%d", &I[x].position);
         }
    }
    
    void output(ind I[], int n)
    {
         int x;
         for(x=0; x<n; x++)
         {
                  printf("NAME: %s\n", I[x].name);
                  printf("AGE: %d\n", I[x].age);
                  printf("GENDER: %s\n", I[x].gender);
                  printf("POSITION: %d\n\n", I[x].position);
         }
    }
    
    int main()
    {
        int n;
        printf("Enter number of registered individuals: ");
        scanf("%d", &n);
        ind I[n];
        int opt;
        do{ 
        printf("1. Add\n2. View\n3. Exit\n\n");
        printf("Option: ");
        scanf("%d", &opt);
        switch(opt)
        {
                   case 1:
                        input(I, n);
                        break;
                        
                   case 2:
                        output(I, n);
                        break;
                        
                   case 3:
                        break;
                        
                   default:
                           printf("INVALID\n\n");
                           break;
        }
        }while(opt!=3);
    }

    Well I recommend you to use Linux instead of Windows. It simplifies the development process if you're not dead tied to Visual Studios, with a very easy-to-use compiler and more text editors to develop in than you could shake a stick at.

    The compiler I use, much like I assume most people here, is gcc. It is a very simple command line tool.

    Disclaimer: I truly enjoy Linux much more than Windows, but as some will undoubtedly be quick to tell you, it is not better. It is just a different method of accomplishing the same task. It's just my preferred method.

    Edit: Kudos for following everyone's advice to the bitter end.

    i have tried a different approach to the program. im using the stuct method rather than typdef struct! this way i'm not using an array to enter information. And it seems to be writing to the file quite well...so far! However i have a problem with output! How do you read from a file from which you dont know how much data is stored? can you use "EOF"?
    and i tried linux ubuntu but ut seemed to be running slow on my laptop :/ i shall try it again!

    You can now start working on your linked list

    I use Windows XP, programming on Code::Blocks (which uses the compiler mingw)

    If you wanted to start a new question, it might be a good idea to start a new thread

    I see your new thread - Ignore this post

    Code::Blocks is a good IDE that I also have used before. It works well, except for the debugger (at least in my scenario)! gdb never fails.

    Also, I would recommend Debian over Ubuntu. Ubuntu is just a system built up over Debian and tends to be too "cutting-edge" for me. Debian Squeeze will run well on your laptop, especially if you install a fast desktop environment like XFCE (that is the one I run).
