Thread: Struct defining in function parameters?

I wanted to define thje player.x before the "int main", it gives errors, that's the reason. I did it define before the function, I didn't explain my problem well.

Now I have another error: expected primary-expression before '.' token. This, in all "case:"es:

Code:

switch(i)
    {
        case '1':
        Player.nx=Player.x--;
        Player.y--;
        break;
        case '2':
        Player.y--;
        break;
        case '3':
        Player.x++;
        Player.y--;
        break;
        case '4':
        Player.x--;
        break;
        //case '5':
        //break;
        case '6':
        Player.x++;
        break;
        case '7':
        Player.x--;
        Player.y++;
        break;
        case '8':
        Player.y++;
        break;
        case '9':
        Player.x++;
        Player.y++;
        break;
    }

What can be the reason of this?

You don't have an instance.

Code:

struct Player
{
  int x;
  int y;
};

void movedir(Player &player, int i)
{
  switch(i)
  {
  case '1':
    --player.x;
    break;
  }
}

Think I have overlooked the real problem.

Code:

void movedir(struct Player,int i) {

is not a valid definiton for a function. should be sth. like this

Code:

void movedir(struct Player player,int i) {
   switch(i)        {
            case '1':player.x--;player.y--;
   ....

edit: seems to be one of theese days where I should not say anything. This is c++ so CornedBee's solution is the right one.
