    Searching through a string....

    I am righting an app that uses a flat file (myVar.txt) to interface with an app I developed in Flash 5, and I'm having a bit of difficulty:

    I am setting the variables fine from both flash and C++, but I am
    trying to sort through an array that I populated as such;

    // Declare the storage array
    char cMyStream[50];

    // Assign the string conents of myVar.txt
    ifstream mystream("\myVar.txt");
    if(!mystream)
    {
    cout << "Cannot open file.\n";
    }

    // Assign the conent of mystream to cMyStream
    mystream >> cMyStream;
    My problem is this...
    the text file uses a variable format of &Var1=234&Var2...
    I want to sort through the variables to return the values of Var1 and Var2 to an array, but lack the knowledge to do so...
    Please help!!!

    If the value for each variable always occurs after the = character, you could use this as the delimeter. Read the characters using getline(), and then read the value into you array of integers.

    mystream.getline(char_buff,sizeof(char_buff),'=');
    mystream >> int_array[i++];

    Put this code in a loop that reads until the end of the file.
