    Question Red or Blue Pill ?

    1-
    Code:
    cout << "Hello EDM/2" << endl;
    I didnt get what does this do

    2- functions initialized like
    Code:
    int functionname(parameter1,parameter2)
    {
       Some actions using parameter1 and parameter2
    }
    ?
    (or adding a "return 0" to end if its not configured to return something like cos(x) etc)

    3- can we use booleans as 1 or 0 (dont answer this one int B2I(bool) would be easy to make)

    4- where can I find a tutorial for using math.h and window.h (I couldnt compile programs in sourceforge so I couldnt find an c++ example application that I can use as tutorial)

    this do print the string "Hello EDM/2" followed by a newline character to the console
    2- functions initialized like
    Code:
    int functionname(parameter1,parameter2)
    {
       Some actions using parameter1 and parameter2

    you didnt ask a question here.

    3- can we use booleans as 1 or 0 (dont answer this one int B2I(bool) would be easy to make)
    try it. its not that hard to just write true or false anyways, and its more readable. its not like its wasting space either.

    4- where can I find a tutorial for using math.h and window.h (I couldnt compile programs in sourceforge so I couldnt find an c++ example application that I can use as tutorial)
    what happens when you compile it? ie what error? for math.h with gcc you have to add '-lm' to link with the math library. maybe something similar for windows.h, ive never had a need to use it so i dont know.
