    Noob Question regarding Pointer-to-Object type

    OK, total noob in C++ here. A little help would really be appreciated. I'm getting a couple errors, and am not sure how to proceed:

    Code follows:

    Code:
    #include <iomanip>
    #include <iostream>
    using namespace std;
    
    int main()
    {
     
    	const int Numgrade = 6;
    	int Score [Numgrade];
    	int Count;
    	int Grade;
    	int Scorein;
    	int av;
    	int sum;
    	int Lowin;
    
    	// Function
    	void Lowscore (int Grade, double Lowin[Numgrade]);
    	{
    	int Scorein[Numgrade];
    	int Lowin[Numgrade];
    
        // Start Function Loop
    	
    
       while (1)
       {
          if (Grade[Lowin]>Grade[Scorein])
          {
             Lowin = Scorein;
          }
          else
          {
          }
          Count =Count+1;
          if (Count>6) break;
       }
    }
    
    // Start Main Loop
       
       cout << "Input Test Scores" << endl;   while (1)
       {
    	  
    	  cout << "Input Test Score" << endl;
          cin >> Score[Numgrade];
          Grade[Count] = Score;
          Count =Count+1;
          if (Count>6) break;
       }
       int Lowin;
      
       Lowscore(Grade,Lowin);
       av =0;
       while (!(Count==Lowin))
       {
          Count =Count+1;
          av =(sum-Lowin)/(Numgrade-1);
       }
       cout << "Your Test Average is "+av << endl;
       return 0;
    }
    Thanks in advance! I know this is pretty basic, but I'm trying to learn!

    First:
    Grade is an integer and not an integer array.

    Several errors.

    You are using int Grade as an array of ints, but you have not declared it as an array of ints. Same with you double Lowin.

    You have declared variable Lowin twice in the same scope as an int. And, you are using it as a double in the arg list for your Lowscore function. So, you've declared it 3 times.

    Move the Lowscore function outside of main. Note that you have "declared" this function, but never "defined" this function.

    Fix those errors and see how it goes.
