Making a word verification in C

**Wimmie07** · 09-03-2018

Hi, I have to make a code where i talk about computer hardware. Now I want to know how to make that when you type further, you go further. else you get the message, sorry, i don't know what you mean.
Here is a bit of the code I already have:

Code:

char nextstap[7]={'v','e','r','d','e','r','\0'};
    puts("Hallo, dit is een programma dat gaat over randapparatuur.\n"); //intro
    puts("We gaan het over verschillende onderdelen hebben maar eerst is het handiger\n");
    puts("om het te hebben over wat randapparatuur nou daadwerkelijk is!\n");
    sleep(1);
    puts("\n");
    puts("Type 'verder' om door te gaan: ");
    if (scanf("nextstap"%c))
        {
            puts("Dit commando ken ik niet!");
        }
    else
        {
            puts("Goed, we gaan verder met de geschiedenis van randapparatuur");
        }
    return 0;
}

The best way forward is to do something like

Code:

char buff[BUFSIZ];
if ( fgets(buff,sizeof(buff),stdin) != NULL ) {
    if ( strlen(buff) == strlen(nextstap)+1 && strncmp(buff,nextstap,strlen(nextstap) == 0 ) {
        // the string is the right length, and matches what we want.
    } else {
        // user typed in either
        // verder + more letters
        // something other than verder
    }
} else {
    // fgets detected eof or error
}
