Calling a function within a function

Hi,

Im trying to call a function within a function but the 2nd function isnt returning anything.
The code compiles fine.

Code:

---

void playerMove(char playerInput,int playerRow,int playerCol,int theGrid[][10])
{
        getPlayerPos(playerRow,playerCol,theGrid);
}

---

its the function getPlayerPos that isnt returning any values.but if I call the getPlayerPos outside of playerMove it works.

Code:

---

int getPlayerPos(int& playerRow,int &playerCol,int theGrid[][10])
{
        for(int row=0;row<10;row++){
                for(int col=0;col<10;col++){
                        if(theGrid[row][col]==1){
                                playerRow=row;
                                playerCol=col;
                                return playerRow,playerCol;
                        }
                }
        }
}

Any ideas?

1) You cannot return two files - only one.
2) If the if statement is never true, the function returns nothing resulting in undefined behavior.

Code:

---

void func1 (int &a) {
  func2 (a);
}

void func2 (int &a) {
  a = 3;
}

---

pass the arguments to 'playerMove' as references aswell if you want to be able to change their values.

Also:

Code:

---

return playerRow,playerCol; /* this is the same as 'return playerCol;' */

---

Ok I understand you both.I see where I was goin wrong.

I know that there is always going to be a 1 value in the array(well there should be!)
I take it that its a bad practice to to leave that if statement open ended should I always qaulify it with an else statement?

thanks for the speedy reply's!

You should have a return at the end of the function to cover the cases if no match was found.

Thanks.
