    dynamic array of structures

    I am doing exercises from a book and it asks that I, "use _new_ to allocate an array [of structures]," I have done it this way:

    Code:
    struct CandyBar	// define CandyBar structure
    {
      char name [20];
      float weight;
      unsigned int calories;
    };
    
    int main()
    {
      CandyBar * pEaster;	// make pointer to Candy bar type
      pEaster = new CandyBar[3]; //allocate mem for 3 CandyBar's
      delete [] pEaster; 	// free memory
      return 0;
    }
    But then I can't figure out how to assign values to the structures' elements. Any help would be greatly appreciated.

    Treat pEaster as an array:
    Code:
    pEaster[0].calories = 100;
    strcpy(pEaster[0].name,"Twix");
    pEaster[0].weight = 10.5f;
    And so on for all the others...

Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."
