    C++ Programming Question Arrays

    Code:
    #include <iostream>
    #include <string>
    using namespace std;
    
    int main()
    {
    
      int scores[48] =
          { 70, 66, 87, 90, 80, 95, 76, 66, 80, 61, 67, 73, 89, 89, 88, 40, 91,
    91, 77, 88, 88, 67, 76, 89, 73, 81, 82, 90, 73, 66, 90, 93, 88, 80, 89, 87 };
    
      string student[16] =
          { "Abbey", "Cecilla", "James", "Todd", "Hellen", "Pat", "Richard",
    "Alex", "Nicky", "Nora", "Paul", "Arthur", "Emillia", "Liv", "Luca", "Teddy" };
    
      cout << scores[0] << student[3];
    
      return 0;
    }
    How do I link the strings to the integers?
    Tx.
    I am totally stumped.

    You mean the fact that there are three scores per student?

    Level 1
    Code:
    int scores[16][3] = {
      { 1, 2, 3 },
      { 4, 5, 6 },
    };
    Level 2
    Code:
    struct student {
      string name;
      int scores[3];
    };
    Level 3
    Code:
    class student {
      private:
        string name;
        int scores[3];
      public:
        // constructor, setters, getters etc.
    };
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    This would be a prefect job for a hashtable.

    No need for a hashtable/tree for a such a simple job of mapping integers from 0...N to an array. In the general case, though, where the range is N...M where N and M are different for every lookup or more types other than integral types, I am willing to agree, though.

    Outside of your DOS world, your header file is meaningless.

    Kevin Konopka, This is not a big deal, but are you aware of the fact that your array only shows 36 element, rather then 48 you called out? Therefore your going to have 12 elements with a value of 0 (zero)
