Thread: Counting vowels in a string - invalid identifier

This is just a small fragment of my code so I didn't include all the vowels.

Code:

    string response;
    int array [5]= {0, 0, 0, 0, 0};


    cout << "enter a string of text\n" << endl;
    cin >> response;
 
      for(int i=0;i<strlen(response);i++)
    {
    if response == 'A'        //invalid identifier
        array[i]++;
    if response == 'E'     //invalid identifier
        array[i]++;
       }

I am getting the error that "response" is not a valid identifier? When I'm trying to check the characters in the string for either A or E and increment the count in the appropriate area of the array...
