Hi! I need help to my c++ program. I created a program that is much like the "Who wants to be a Millionaire" television show. It has questions and the right answers and three lifelines. How can I possibly do eliminate a lifeline after being used.?

this is the program I created so far:

#include<iostream.h>
#include<conio.h>
#include<stdlib.h>
void box(int x, int xx, int y, int yy);
void box(int x, int xx, int y, int yy)
{
int xs,ys,i,j;
xs=xx-x;
ys=yy-y;
for(i=1; i<xs; i++){gotoxy(x+i,y);cout<<"Í";
		    gotoxy(x+i,yy);cout<<"Í"; }
for(j=1; j<ys; j++){gotoxy(x,y+j);cout<<"º"; }
for(j=1; j<ys; j++){gotoxy(xx,y+j);cout<<"º"; }
		   {gotoxy(x,y);cout<<"É";
		    gotoxy(x,yy);cout<<"È";
		    gotoxy(xx,y);cout<<"»";
		    gotoxy(xx,yy);cout<<"¼";}
}
char name[50];
char ans;
char ask;
int life;

before trying to implement eliminating lifelines I think you code is in desperate need to refactoring to put common code in functions that can be called.

For example:

A function that asks the question
Parameters:
The question
The 4 answers
The right answer
Returns a flag indicating if the question was answered correctly

A function that asks for a lifelline number
No parameters
Returns the number of a valid and available lifeline

In addition to what Banfa said, you need to learn formatting. Your code is completely unreadable. You should not ask someone else to try and help you with code that cannot be followed.

As for lifelines, you need to keep track of all three individually. Use an array.

Thanks for the reply! I really don't have any idea what "Parameters" you are talking about, I'm only just a beginner and what my teacher teach is only the basic. We haven't reach that too far. (^_^) I'll try to google it on my own. Thanks! and I'll be glad if you could still help figuring these things out for me. lol. Thanks again.

... what my teacher teach is only the basic.

No, what your teacher teaches is completely non-standard C that cannot be used in today's industry. TurboC++ is over 17 years old and is so outdated at least 3/4ths of your code cannot possibly be compiled on any current compiler. TurboC 3 I assume? Makes it almost 20 years old.

I hope you aren't paying a lot for your C++ class. You are getting ripped off.
