Question

Doing some practice questions to prepare for a test next week for C++ and need some help figuring these out. The focus is on arrays. I've done the large majority of them but these are the ones I'm struggling with.

Explanation / Answer

1.
   cin >> A[5];
   cin >> A[9];
   Sum = 0;
   for(int i = 0; i<10; i++){
      Sum = Sum + A[i];
   }

2.    cin >> n;
      for (int i = 0; i<n; i++)
          cin >> A[i];
      for (int i = n-1; i<=0; i--)
          cout << A[i] << " ";

3. cin >> Q[5];
   cin >> Q[2];
   NegSum = 0;
   for(int i = 0; i<8; i++){
      if (Q[i] < 0)
         NegSum = NegSum + Q[i];
   }

4.
    PLAYER data[20];
    int numPlayers;
    Load_Game(numPlayers, data);
    double sum = 0;
    for (int i = 0; i<numPlayers; i++){
        sum = sum + data[i].Pts;
    }
    cout << setprecision(1) << sum/numPlayers << endl;

5.    cin>>CAP;
      int pos;
      int *EVEN = new int[CAP];

      int a = 0;
      for (int i = 0,; i <CAP; i = i++){
          EVEN[i] = a;
          a = a+2;
      }
         

      cin << pos;
      cout << EVEN[pos-1];

6     char A[7];
      int i1,i2,j1,j2;
      char a,b
      for (int i = 0; i<7; i++)
          A[i] = 'Z';
      cin>>i1 >> i2 >> a >> b >> j1 >> j2;
      A[i1] = a;
      A[i2] = b;
      cout << A[j1] << A[j2];

7.    int A[25];
      int n;
      Load(n,A);
      int num = 0;

      for (int i = 0; i<n; i++)
          if (A[i] <0)
             num++;
      cout << num;

8.   
      cin >> A[2] // This is in main for taking the input.Following is the body of the function

      for(int i = arraySize-1; i <= 0; i--)
          cout << array[i] << " ";
      cout << endl;
