(adsbygoogle = window.adsbygoogle || []).push({}); ok so i have created a simple subtracting game but i have found it is way to hard to beat. so i want to add the option to use two players and still have single player. i have coded this whole single player program inside of the main function but what i want is to move this chunk of code inside of a user defined function and then code another function called twoplayer then use a simple switch statement inside the main function to all the selected mode. i am having trouble in creating the function. i have tried declaring void twoplayer() ....MAIn FUNCTION HERE... followed then by a copy and paste of the important code inside the twoplayer function.

right now i do not have access to my program but if no one has suggestions then i will get it and post it here. thanks in advance.

i see, you want the same mechanics but implement them into 2 player.
i dont understand the game, but you need to ask for the input of the 2nd player and replace it with the answer of the ai.

i dont know if that makes any sense to you

Yeah i know what you mean and i know how i will create both modes the problem is, is that i need to create two functions but i dont know how. I think i am titling them wrong i use
Void oneplayer{copy and paste from main} i will upload the code tomorrow but thanks

You should upload your code as soon as possible, it's hard to fix a problem without context.

agreed with epic? would be much quicker of a problem solved if we could see your code.

and it shouldn't be too hard. you can get two users input by using cin>>variable;
or use getline depending on how your game works.

ok heres my code i have single player just how i want it and multiplayer wont be to hard.

#include <iostream>
using namespace std;

int main()
{
char playagain = 'y';

do
{
int number, total = 21;
system("CLS");

cout << "Welcome to snigs super subtracting game." << endl << "The rules are:\nyou will take 1 or 2 away from the total number.\nthen the computer will do the same.\nthe first one to get the number to 0 wins." << endl;
cout << "\nThe total is: " << total << endl;
while (total >= 0)
{
cout << "----------------------------------------\n";
cout << "Your Turn.\n You MUST choose 1 or 2.\n";
cin >> number;

while(number < 1 || number > 2)
{cout << "this is an invalid number try again.\n";
cin >> number;
}
total = total - number;
cout << "The new total is " << total << endl;

if (total == 0)
{cout << "**YOU WIN.**";
break;}

cout << "Computers turn.\n";
if ((total % 3) == 2)
{
cout << "Im going to subtract 2.\n";
total = total - 2;
}
else
{
total --;
cout << "\nI am Subtracting 1.\n";
}
cout << "\nThe new total is: " << total << endl;
if (total == 0)
{
cout << "\n**I WIN YOU'RE A LOOSER.**\n";
break;
}

}
cout << "\ndo you want to play again? (y/n)";
cin >> playagain;
while (playagain != 'y' && playagain != 'n'
{
cout << "\ninvalid input detected try again: ";
cin >> playagain;}


}while (playagain == 'y';
cout << endl;
system ("PAUSE");
return 0;
}


i just need to take all of the code inside of main and turn it into a function. so that later on i can just use the two functions in a switch statement. i am sort of new to this but im sure it can be done. thanks

ok guys i have made some progress on what i want it to do. here is the new code. it doesn't work but its ok becuase thats just fine tuning.




#include<iostream>

using namespace std;

void single(void);
void two(void);

int main()
{
int choice;

cout << "Enter 1 to play single player/Enter 2 to play with a friend." << endl;
cin >> choice;

if (choice == 1){
single();}
if (choice == 2){
two();}
//if (choice 1 < || > 2){
//cout << "Invalid Choice Try Again." << endl;
//
//cin >> choice;}

system ("PAUSE");
return 0;}


void single(void)
{
char playagain = 'y';

if you look you can see my int main is very short that i what i ment at the start.

this code is not huge

ikr, that wasn't too hard
