Thread: Namelist in C

Hey guys
My code needs to save a list of names from a file and sort out the ones who are appearing several times. A pointer array should be used for the strings.

I already wrote a code but it doen't works. It crashes when I try to start is.

Heres my code:

Code:

#include <stdio.h>#include <stdlib.h>
#include <string.h>


int main()
{
    char *namen[500];
    char InputBuffer[255];
    int x=0, i, j, anzahl=0;
    FILE* pDatei;
    pDatei=fopen("Vornamen.txt","r");


    while(fscanf(pDatei,"%s",InputBuffer)!=EOF)
    {
        for(i=0;i<=x; i++)
        {
            if(namen[i]==InputBuffer)
            {
                break;
            }
            else if(i==x)
            {
                namen[x]=InputBuffer;
                x=x+1;
            }
        }
    }


    fclose(pDatei);
}

So can you find an error, cause for me it should work.

I'm programming with code::bloxx btw.

Thankfull for very Hint

Additional comments:

Code:

pDatei=fopen("Vornamen.txt","r");

You should ensure the file has opened successfully before attempting to access it.

Code:

namen[x]=InputBuffer;

To copy strings, use strcpy().

Code:

char *namen[500];

This gives you an array of uninitialized pointers. If you want to store strings, you need to allocate memory to each pointer.
