Getting Started with C++ 2014

Steps are as follows:

Download gcc v5.1.0 32-bit from

ftp://ftp.equation.com/gcc/gcc-5.1.0-32.exe

Install gcc v5.1.0 32-bit to "C:\gcc-5.1.0-32"

Download and install Notepad++ from

https://notepad-plus-plus.org/download/

The Path environment variable to run C++ 2014 on Windows 7 is configured automatically.

If not, open the Environment Variables frame through "Control Panel\System and Security\System".
Hit the end key to scroll to the end of the variable value textbox of variable name Path.

Then, type a semicolon at the end of the existing path, followed by the gcc executable binary directory, which is as follows:

;C:\gcc-5.1.0-32\bin;C:\gcc-5.1.0-32\libexec\gcc\i686-pc-mingw32\5.1.0

Restart your computer because of the installation of gcc v5.1.0 32-bit.

Open Notepad++

Save the new file as "cpp2014_no1.cpp"

File name: cpp2014_no1.cpp

File content:

/**********/

#include <iostream>

using namespace std;

int main(int argc, char* argv[])

    //binary literal
    auto binary_literal = 0b0001'1111;
    cout << binary_literal << endl;
   
    //digit separators
    auto integer_literal = 1'000'000;
    cout << integer_literal << endl;
   
    //generic lambda function
    auto lambda = [](auto x, auto y) {return x + y;};
    auto sum = lambda(1.2, 3.4);
    cout << sum << endl;
   
    return 0;
