Getting Started with C++ 2017 using gcc v6.1.0 32-bit

Steps are as follows:

Download gcc v6.1.0 32-bit from
ftp://ftp.equation.com/gcc/gcc-6.1.0-32.exe
Filename: gcc-6.1.0-32.exe

Install gcc 32-bit to "C:\gcc-6.1.0-32"

Please log off and log in again to configure the gcc for all users on this operating system.

Download and install Notepad++ from
https://notepad-plus-plus.org/download/

Open Notepad++
Save the new file as "cpp2017_eg1.cpp"

Filename: cpp2017_eg1.cpp
File content:
/********************/
#define __STDCPP_WANT_MATH_SPEC_FUNCS__ 1 //betaf(), beta()
#include <iostream>
#include <string>
#include <experimental/string_view>
#include <cmath>
using namespace std;

int main()
{ 
    cout << __cplusplus << endl; //201500

    //Hexadecimal literals
    int hex1 = 0xA;  
    cout << hex1 << endl; //10  
  
    experimental::string_view v = "hello world";
    v = v.substr(7);
    cout << v << endl; //orld

    //Mathematical special functions from C++ 2017
    cout << betaf(4.0f, 2.0f) << endl; //0.05

    int n = 4;
    int k = 2;
    cout << 1/( (n+1)*beta(n-k+1, k+1) ) << endl; //6
    // C(4,2)=4!/(2!2!)=4x3/2=6
  
    cout << expint(1) << endl; //1.89512, exponential integral
    cout << riemann_zeta(2) << endl; //1.64493          
  
    return 0;
}

Step to uninstall GCC downloaded from
http://www.equation.com/servlet/equation.cmd?fa=fortran
* Open the system “Environment Variables” frame
* Delete the system variable named “EQ_LIBRARY_PATH” which contains the following variable value "C:\gcc-6.1.0-32\i686-pc-mingw32\lib"
* Delete the following two system path values from the system variable named “Path”:
*** "C:\gcc-6.1.0-32\bin;”
*** “C:\gcc-6.1.0-32\libexec\gcc\i686-pc-mingw32\6.1.0;"
* Delete the directory at “C:\gcc-6.1.0-32”
