i am having a struggle with understanding this code properly. Is whatIsThis a proper name for the class on functions of the program or should it be something else. I have not been able to manage to get the program compiled with the source code 

//Ex. 7.18: Ex07_18.cpp

//What does this program do?

#include <iostream>

using std::cout;

using std::endl;

int whatIsThis(int[], int); // This is the function prototype which tells the

// compiler that program would have the definition of

// a function named whatIsThis and would have the parameters

// integer array and an integer value

 

int main()    // main function

 

{

       const int arraySize = 10;  // declares a constant integer variable and initializes it to 10

       int a[arraySize] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };  // declares an array a with size arraySize and initializes it

 

       int result = whatIsThis(a, arraySize);   // it calls the function whatIsThis and passes array a and arraySize values and receives

       // an integer value from the function

 

       cout << "Results is " << result << endl; // prints the result to the console output

       return 0; //indicates successful termination

} // end main

 

// This function recursively finds the sum of the elements in the arrau

int whatIsThis(int b[], int size)

{

       if (size == 1) // base case, at this case it will terminate the recursive function

              return b[0];

       else // recursive step, at this it would call itself again recursively to add the next element into the sum

              return b[size - 1] + whatIsThis(b, size - 1);

} // end function whatIsThis
