Thread: Simple Menu Program

Hi there I'm fairly new to programming, I decided to create a simple program to display a menu with options, while that is easy enough I had some difficulty when selecting an option that has options inside which also has an option again (sorry for the confusion). While I had many issues in the past I'm finally finished with it and it works fine, but being new to programming and not knowing various other methods available, would you say this is the most efficient way of creating what I needed? or is there a far more optimized way??

Code:

//:::::::::::::::::::::Simple Menu Program::::::::::::::::
//::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

#include <iostream>
#include <string>


//function prototypes
//========================================
void Menu();
void Story();
void Bios();
void Player1();
//========================================

//global variables
//========================================
int choice(0); //selection variable
//========================================


int main()
{

    do//while in the Menu() function display it untill the user selects option 3
    {
    system("CLS");//clear screen of any previous or future menus
    Menu();//display the main menu
    std::cin >> choice;//user inputs choice

    switch(choice)//determine what happens based on choice
    {
    case 1://if option 1 is selected
        system("CLS");//clear the screen
        Story();//display the games story
        std::cin >> choice;//get choice from player
        if(choice == 1)//when in Story() if option 1 is selected
        {
        system("CLS");//clear screen
        Menu();//return to the Main Menu
        }
        else if(choice == 2)//when in Story() if option 2 is selected then
        {
        exit(0);//exit program
        }
        break;
    case 2://if option 2 is selected in the Main Menu
        system("CLS");//clear the screen
        Bios();//display the Bios() menu
        std::cin >> choice;//user inputs choice
        if(choice == 1)//when in Bios() if option 1 is selected
        {
        system("CLS");//clear screen
        Player1();//display p1's bios

//---------------------------------------------
//in p1's bios you have the option to press 1 to go back to Bios() or 2 to exit
//---------------------------------------------
        std::cin >> choice;//get input of 1 or 2 from user
        if(choice == 1)//if option 1 is chosen
        {
        system("CLS");//clear screen
        Bios();//display Bios() again
        std::cin >> choice;
        }
        else if(choice == 2)//while viewing p1's bios if selecting option 2 then exit
        {
        exit(0);
        }
        }
        else if(choice == 2)//when in Bios() if option 2 is selected
        {
        system("CLS");//clear screen
        Menu();//display Menu()
        }
        break;
    case 3://if option 3 is selected
        exit(0);//terminate the program
        break;//necessary??
    }

    }while(choice!=3);

return 0;
}

void Menu()//Main Menu layout
{
    std::cout << "::::::::::Main Menu::::::::::\n" << std::endl;
    std::cout << "1) Game Story" << std::endl;
    std::cout << "2) Character Bios" << std::endl;
    std::cout << "3) Exit Program\n" << std::endl;
    std::cout << "Please select an option: ";

}

void Story()//Game Story
{
    std::cout << "::::::::::Game Story::::::::::\n" << std::endl;
    std::cout << "This is the story of the game...\n" << std::endl;
    std::cout << "press 1 to return to the main menu or 2 to exit the program: ";

}

void Bios()//Bios Menu layout
{
    std::cout << "::::::::::Bios Menu::::::::::\n" << std::endl;
    std::cout << "1) Player 1" << std::endl;
    std::cout << "2) Back" << std::endl;
    std::cout << "Please select an option: ";

}

void Player1()//Player 1 Bios - I will use a class and objects later for this info
{
    std::cout << "::::::::::PLAYER 1::::::::::\n" << std::endl;
    std::cout << "Name: Player 1" << std::endl;
    std::cout << "Age: 300" << std::endl;
    std::cout << "From: Unknown" << std::endl;
    std::cout << "Height: 7.0ft" << std::endl;
    std::cout << "Weight: 430lbs\n" << std::endl;

    std::cout << "press 1 to return to the main menu or 2 to exit the program: ";


}

hmm, while I said it works I have noticed a couple of bugs .. if you select character bios then select player 1, then go back to the bios menu, then select player 1 again it doesn't show player 1's bios, instead it returns to the main menu. I feel my code isn't very efficient.
