    fscanf problems

    Hi, this is a simple task but i've been breaking my head over it for a day and can't figure out what the problem is. Any help would be good.
    #include <stdlib.h>
    # include <string.h>
    #include <stdio.h>
    #include <stdint.h>
    int main(){
    char key[10];
    strcpy(key, " ");
    FILE *pFile = fopen("testing", "a");
    fprintf(pFile, "HELLO WORLD");
    int i = fscanf(pFile,key);
    if (i=EOF){
    printf("%s\n", key);
    return 0;
    Why is this printing EOOOOF then blank? I just want a simple program that reads from a file and stores a string without white spaces into a string. This is a simple task but for some reason it's always scanning from the end of the file therefore returning blank spaces into the string. Thank You for any help.

    For one, you are trying to read from a file that was opened for appending. Try:
    FILE *pFile = fopen("testing", "a+");
