    c:\windows\desktop\to u.cpp:13: `name' undeclared (first use this function)
    c:\windows\desktop\to u.cpp:13: (Each undeclared identifier is reported only once
    c:\windows\desktop\to u.cpp:13: for each function it appears in.)

    Ask, and ye shall recieve....you MUST declare a variable before using it!!

    Code:
    #include <windows.h>
    #include <iostream.h>
    #include <stdio.h>
    #include <stdlib.h>
    
    int main()
    {
    char name[100]; //...declaration!
    
    cout << "Hello World!" << endl;
    
    cout << "enter your name:";
    
    cin.getline (name, sizeof (name));
    
    cout <<"\ngreetings, "<< name << "\n";
    
    cout << "Press ENTER to continue...";
    
    cin.get(); //...'pause' screen...
    
    return 0; //...main returns an integer.
    }
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }

    gamer, did you read the errors first, my advice to you is try reading them first, and try solving the problem yourself...
    none...
