i an thinking of making a slot machine program in c++
here is what it should do. roll slots, randomly generates the number. for everytime you win, you get 4 dollars, every play costs 1 dollar. the random number should be somewhere between 1 to 5. if the random number is all fives the player gets 100 dollars. Here is what i have so far, but its not working. Could you please tell me what to do.

Code:
#include <iostream>
#include <cstring>
#include <stdlib.h>
#include <time.h>

using namespace std;

void Slotstart ();
void Slotplay ();

int money;
int maxrand;
int result;
int rannum;
int winnum;

int main()
{
  char name[50];
 
  cout<<"Please enter your name: ";
  cin.getline ( name, 50 );
  cout<<"Welcome to Virtual Slot machine, "<< name  <<" \n";
  cout<<"Press enter to continue\n";
  cin.get();
  Slotstart();
}

void
Slotstart ()
{

     money = 2;
     maxrand = 2;
     
cout<<"Press enter to pull the slot machine.\n";
cout<<"Press ""leave"" anytime to stop playing.\n";

cin.get();
srand( (unsigned)time( NULL ) );
rannum = rand() % maxrand;
Slotplay ();

}

void
Slotplay ()
{

... um ... finish writing your code?

Actually, before you do that, I strongly recommend designing the entire program in pseudocode .. THEN flesh it out with proper C++ code. That way, you can think your way through the problem before you try to translate it into a language with which you are largely unfamiliar.

here it is, but it won't compile, it says something about SlotRestart() can't be used as a funtion or void.

Code:
#include <iostream>
#include <cstring>
#include <stdlib.h>
#include <time.h>

using namespace std;

void SlotRestart;



int slota;
int slotb;
int slotc;


int main()
{
  char name[50];
 
  cout<<"Please enter your name: ";
  cin.getline ( name, 50 );
  cout<<"Welcome to Virtual Slot machine, "<< name  <<" \n";
  cout<<"Press enter to continue\n";
  cin.get();


     
cout<<"Press enter to pull the slot machine.\n";
cout<<"Press ""leave"" anytime to stop playing.\n";
cin.get();

srand(time(0));
    slota=rand()%3;
    slotb=rand()%3;
    slotc=rand()%3;
   
    if(slota==slotb && slotb==slotc && slotc==slota)
    cout<<"You win\n";
   
    else
    cout<<"You lose\n";
    cin.get();
    SlotRestart();
}

void
SlotResult ()
{
        cout<<"Press enter to pull the slot machine.\n";
cout<<"Press ""leave"" anytime to stop playing.\n";
cin.get();

srand(time(0));
    slota=rand()%3;
    slotb=rand()%3;
    slotc=rand()%3;
   
    if(slota==slotb && slotb==slotc && slotc==slota)
    cout<<"You win\n";
    SlotRestart();
   
    else
    cout<<"You lose\n";
    cin.get();
    SlotRestart();
}

change void SlotRestart; to void SlotRestart(); line 8

change void SlotResult (){ to void SlotRestart(){ line 47

add curly brackets to the last if block (in SlotRestart()) lines 58 to 66

i changed it to what mag said, but now it highlights "else" in slot 64. It says:

In funtion 'void SlotRestart()'
expected primary-function before 'else'
expected ';' before 'else'

thanks

These are simply syntax errors .. you need to learn to debug these if you intend to do any programming.

What book are you using to learn? Is this for a course?

i fixed it by deleting void SlotRestart in line 62, but now if you run it, it will do you lose for about 20 times in a row, and then you win for 5 times in a row, and you lose 20 times in a row, and so on.

look over their guide on if structures again

hint, you want
Code:
cout<<"You win\n";
SlotRestart();


to execute if they win

you want
Code:
cout<<"You lose\n";
cin.get();
SlotRestart();

to execute if they lose

i want SlotRestart to start no matter what, so they don't have to reopen the program to play the slot machine again.

Hint: Always use braces with if statements. It makes your life a lot easier and avoids problems like you have currently

Good advice, at least until you get better with the syntax...

You know, this would be a good situation for a do...while statement.
