    Unhappy File Handling?!?

    Ok, I asked this before. I've tried the suggestions and have failed. This is what I want to do.

    I have a question.txt file that looks like this.
    Question 1: Yadda yadda
    Answer: TRUE
    Question 2: Yadda Yadda
    Answer: FALSE

    Now how would I make a program read from that file, print the question, ask for user input then check the answer against the answer in the text file? I think I can figure out the user input part, but I just need help with the file handling part. Any help would be appretiated.

    A bit like this perhaps
    #include <stdio.h>
    int main ( int argc, char **argv ) {
        FILE *fp = fopen( "question.txt", "r" );
        char question[BUFSIZ], answer[BUFSIZ], my_answer[BUFSIZ];
        while ( fgets( question, BUFSIZ, fp ) != NULL ) {
            fgets( answer, BUFSIZ, fp );
            printf( "%s", question );
            fgets( my_answer, BUFSIZ, stdin );
            if ( strcmp( answer, my_answer) == 0 ) {
                // correct
            } else {
                // wrong
        return 0;
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
