variable-size type declared outside of any function

^ that is the error i get ^

i am declaring 2 global variables:

PHP Code:

---

// Global Variables
int MAXPLAYERS;
int players[MAXPLAYERS+1]; 


---

i need these global because i have my program in all different functions, and they all must access the players[] array. Does anyone have any ideas about what i could do?

[INFO]
I am making a program that helps with tournaments ( Lets the user enter all the data and the program seeds them and displays pairings )

I am using the MinGW Compiler (with the command line)

I am running Windows 98 SE, but in a couple minutes i will install Windows ME
[/INFO]

>int MAXPLAYERS;
>int players[MAXPLAYERS+1];

Is it valid to declare players like this? Shouldn't be the size of the array a constant?

If you declare these variables global, then there available to all functions just by using their names.

Code:

---

file 1:

int global_variable;

void function (void)
{
    global_variable = 1;
}


file 2:

extern int global_variable;

void other_function (void)
{
    printf ("Value of global_variable is %d\n", global_variable);
}

---

change this:

Code:

---

int MAXPLAYERS

---

to this:

Code:

---

const int MAXPLAYERS = 100;  //for example

---

Also, why would you have a variable called MAXPLAYERS then add 1 to it for the array, shouldnt it be MAXPLAYERSMINUSONE :P

You haven't defined the size of MAXPLAYERS, so [MAXPLAYERS
+1] isn't defined either. The stuff in square brackets is
the array dimensions, and those have to be set whenever
you declare the array. It looks like what you're trying
to do is create an array that changes in size, and as far
as I know, that is illegal in C++.

no, i will just disregard the players[0]; because i dont want there to be a #0 Player so i add one to the array so i can have 1 to MAXPLAYERS instad of 0 to MAXPLAYERS-1

I need the user to enter how many players will be playing (MAXPLAYERS) and want that array to size it's self according to that

Would a vector work in this situation?

Then you need to have the input routine before you declare
the array. As I said before, you can't have an
unspecified array size upon declaration. If the compiler
doesn't know how big the array is at the time the array is
declared, it will tell you so and refuse to compile.

Yeah.. std::vector is the easiest way to do this.
