    Scanning Strings till no white space is found?

    Hey Guys

    Have tried the forums but failed to find a solution.

    How can i scan a string lets say " homer1 = 2+1"
    so that i am given the position as an integer of the first charector that is not a white space.

    I have tried:

    int temp = string1.find_first(!(' '));

    but even i knew that wouldnt work d'oh!

    can anyone help me out?

    Thanks in advance

    Maybe...
    Code:
    string string1( " homer1 = 2+1" );
    int iPos = string1.find_first_not_of(' ')
    Something like that I think, I've never used that string member function so I could be wrong about its usage.
