below is code that would display the game title,authors of it,then a menu..first if there's nothing that have been save the only menu that would appear are new game,top score and quit...but if you'll change or there's a save game it has a continue menu...
the other thing is that i let the userinout and the check be on a upper case so that it would convert the userinput even he/she input a lower case choice..
the only thing a headache is that how could a catch that if the userinput is a word or a numbers it is invalid...
please help me...

#include<iostream>
#include<string>
#include<ctype.h>
using namespace std;
class tech
{
public:
	string title;
	string gname;
	string que;
	string choicesA,choicesB,choicesC;
	char check,userinput;
	string menu;
	int cnt;


	void displaytitle(string title);
	void displaygname(string gname);
	void displayque(string que);
	void displaychoices(string choicesA,string choicesB,string choicesC);
	void displaycheck(char check);
	void displaymenu();

};
void tech::displaytitle(string title){
	cout<<title<<endl;
}
void tech::displaygname(string gname){
	cout<<gname<<endl;
}
void tech::displaymenu(){
	cout<<"Select Menu:\n(1)New Game\n(2)Top Score\n(3)Quit\n";
}
void tech::displayque(string que){
	cout<<que<<endl;
}
void tech::displaychoices(string choicesA,string choicesB,string choicesC){
	cout<<choicesA<<choicesB<<choicesC<<endl;
	
}
void tech::displaycheck(char check){
	cin>>userinput;
	if(topupper(userinput)==topupper(check))
	{
		cnt=0;
		cnt = cnt + 1;
		cout<<cnt;
		cout<<"correct";
	}
	else{
	cout<<"invalid";
	}
}

main ()
{
	int c;
	tech first;
	first.displaytitle("WELCOME Game Name");
	first.displaygname("authors");
	first.displaymenu();
	cin>>c;
	switch(c)
	{
	case 1:
	first.displayque("First question...");
	first.displaychoices("a.choice","b.choices","c.choosen");
	first.displaycheck('a');
	break;
	case 2:
		cout<<"top score";
		break;
	case 3:
		cout<<"quit";
		break;

	}
	return 0;

Use [code] tags

[John]

Place your code between CODE tags. ie)

[noparse]

#include <iostream>
...

[/noparse]

Using a question mark in there somewhere might have indicated to me some form of question. I'm sure there is at least one there, but I don't know what you might be trying to ask.

I believe that his question is;

"How can I make sure that the userinput is a word, or numbers, and that it is valid."

You can use strcpy, strcat, or if it's like 1 character; if (variable == 'Character') (or if it's multiple, cases would do)

I'm sure there will be other ways, perhaps better too.

You are already including ctype.h for toupper, the same header gives you access to isalnum and isalpha which check to see if the input is alphanumeric and alphabetic.

see here for a full list of the function in the ctype.h header

[joie2]

how could i catch the userinput if it will enter a string or a word..word with a number or numbers....

[dcs]

If you are trying to verify that user input for a numeric value is indeed a number, check out the snippets linked here:

http://forum.codecal...-numbers-c.html

And read the tutorial for its full value as well.
