    do your own homework.
    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;
    }

    Simple enough:
    Code:
    #include <iostream>
    int main() {
    	std::cout << "Enter words (q to quit):\n"
    		"The 12 awesome oxen ambled\n"
    		"quietly across 15 meters of lawn. q\n"
    		"5 words beginning with vowels\n"
    		"4 words beginning with consonants\n"
    		"2 others";
    }

    Header File

    ctype.h

    Category

    Classification Routines

    Syntax

    #include <ctype.h>

    int isalpha(int c);

    int __iscsymf(int c);

    int iswalpha(wint_t c);

    #include <mbstring.h>
    int _ismbcalpha(unsigned int c);

    Description

    Classifies an alphabetical character.

    isalpha is a macro that classifies ASCII-coded integer values by table lookup. The macro is affected by the current locale's LC_CTYPE category. For the default C locale, c is a letter (A to Z or a to z).

    You can make this macro available as a function by undefining (#undef) it.

    Return Value

    isalpha returns nonzero if c is a letter.

    __iscsymf returns true if and only if the argument c is a letter or an underscore.

    iswalpha returns nonzero if c is a wchar_t in the character set defined by the implementation.

    _ismbcalpha returns true if and only if the argument c is a single-byte ASCII English letter.
    that's your clue - now get to work.
    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;
    }

    What the guys are trying to say is we won't write your code for you. You must post the code you have and we can help you fix it... But you have to do most of the work.

    And 'dis' is spelled with a th, not a d. We aren't inner-city ghetto types here. At least some of us aren't.
