(adsbygoogle = window.adsbygoogle || []).push({}); Well, I got bored so I wrote a C++ base app. When writing an app the beginning code is the same mostly (if it's console apps lol), anyways go through this and see what I mean. I wrote all of this so I give full permission to use and release your app. All I ask is to not tell people you made the app without this thread if you use. Anyways, here it is lol.
Also, I'm sure there is a easier way to code this, but I was bored so I was figuring some stuff out by the way I coded this :p

Built in Visual C++ 2010

It looks like this:
You must login or register to view this content.

    

#include "stdafx.h"

#include <iostream>

#include <Windows.h>

#include <conio.h>

#include <string>



// Define colors

void setColor(int e) {

	SetConsoleTextAttribute(GetStdHandle (STD_OUTPUT_HANDLE), e);

}



// Define pause 

void pause() {

	_getch();

}



// Define clear

void clear() {

	system("CLS");

}



// Define spacer (\n)

void _space(std::string i = "\n") {

	using namespace std;

	using std::string;



	cout << i;

}



// Define spacer2 (\n\n)

void _space2(std::string l = "\n") {

	using namespace std;

	using std::string;

	

	cout << l << endl;

}



// Define text

void printText(std::string e) {

	using namespace std;

	using std::string;



	cout << e;

}



// Define directions

void dir_init() {

	setColor(14);

	printText("Press A to say hello world!"); _space();

	printText("Press B to say Hello World!!"); _space();

	printText("Press C to say Hellow world!!!"); _space();

}



// Define header

void _header() {

	setColor(12);

	printText("========================= ::: "); printText("Name of Application"); printText(" ::: ========================="); _space();

	printText("Build <number>"); _space();

	printText("Created By: <name>"); _space();

	printText("================================================================================");

	_space2();

	dir_init();

}



// Button handling

void but_init() {

	char ch;

	while(true) {

		ch = _getch();

		if (ch == 'a' || ch == 'A' {

			printText("hello world!"); _space();

		} 

		else if(ch == 'b' || ch == 'B' {

			printText("Hello World!!"); _space();

		}

		else if(ch == 'c' || ch == 'C' {

			printText("Hello world!!!"); _space();

		}

		else {

			clear();

			printText("Please press the correct options from the menu!"); _space2(); _space2();

			_header();

		}

	}

	pause();

}



int main() {

	using namespace std;



	SetConsoleTitle(L"Title of the console ie: app name");

	_header();

	but_init();

	return 0;

}

this is really good and all, but it can be shorter and you used a lot of unnecessary includes.
i would have used. just this.

    

#include <iostream> 

using namespace std;

void opt1();

void opt2();

void opt3();

void opt4();

void opt5();

void (*options[5])()=

{

	opt1,opt2,opt3,opt4,opt5

};

int main()

{

	int ans;

	cout << "Welcome to the menu system\npress 1 -- say hello world!\npress 2 -- say hello word!\npress 3 -- say hello word!\npress 4 -- say hello word!\npress 2 -- say hello word!\nEnter Choice: ";

	cin>>ans;

	switch(ans)

	{

		case 1: options[0]();

		system("pause>nul");

		break;

		case 2: options[1]();

		system("pause>nul");

		break;

		case 3: options[2]();

		system("pause>nul");

		break;

		case 4: options[3]();

		system("pause>nul");

		break;

		case 5: options[4]();

		system("pause>nul");

		break;

		return 0;

	}

}

void opt1()

{

	cout<<"Hello, World!"<<endl;

}

void opt2()

{

	cout<<"Hello, World!"<<endl;

}

void opt3()

{

	cout<<"Hello, World!"<<endl;

}

void opt4()

{

	cout<<"Hello, World!"<<endl;

}

void opt5()

{

	cout<<"Hello, World!"<<endl;

}

then to further shorten it we could just make the functions in a .h file and include that.

As I stated above "Also, I'm sure there is a easier way to code this, but I was bored so I was figuring some stuff out by the way I coded this :p"

well my way was using array of function pointers which will help in functionality overall. allowing someone to do something like.

if (choice == 1){
functions[0]();
}
else if(choice == 2){
functions[1]();
}

where the given functions could be login, and edit profile or something along those lines.
