    Adding stuff to strings from files..

    This is probably very stupid, but I'm a beginning programmer and I'd like your help.
    I have a text-file with lines like this:

    bla bla bla !end!

    Now I want my program to ad all the words from a line to a variable, until it reaches "!end!". So if my program would read from the above line the value of the variable would be "bla bla bla". I tried it with this (only a small piece):

    Code:
    ifstream my_file("rode.txt");	
    my_file>>part_of_total;
    while (part_of_total!="!end!")
    {
    strcat(totalname," ");
    strcat(totalname,part_of_total);
    my_file>>part_of_total;
    }
    I know, my coding in general sucks But do you guys have tips or something for me to achieve this?
    Doesn't have to be an anhanced methode of my coding, new coding would rock
    Thanx in advance!

    look up strcmp() in your help files or favourite text book. You cannot compare C style strings with != operator.
    strcmp() returns 0 if the strings are equal.
    Free the weed!! Class B to class C is not good enough!!
    And the FAQ is here :- http://faq.cprogramming.com/cgi-bin/smartfaq.cgi

    You can't simply do:
    while(x!="!end!")

    You must either use a strtok function or parse the string letter by letter.

    Like:

    for(i = 0; i<strlen(string); i++)
    {
    if(string[i] == '!')
    break;

    else
    temp[j] = string[i];

    j++;
    }

    use strcmp to compare and then use strcat to combine the strings.
