    Prog Book Error

    Can anyone see why this code produces letters and numbers and not the numbers 0 - 14? I think the author made a typo somwhere. It is suposed to be a shorter version that having to use a for loop to literate through the array elements. I get no errors or warnings.

    Code:
    #include <iostream>
    
    using std::cout;	
    using std::endl;
    
    // main function - where program execution begins
    int _tmain(int argc, _TCHAR* argv[])
    {
    	const int ArraySize = 15;
    
    	int n[ ArraySize ] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 };
    
    	cout << "My array: " << n << " ";
    
    	getchar();	// need to freeze output in debug mode
    
    	return 0;	// indicates program ended sucsessfully
    }

    that only displays the address of the array, not the individual array elements. Suggest you go to the publisher's web site and see if there are corrections to that book -- most publishers have them free for the downloading.

    and I wouldn't trust any book that attempts to teach c++ and winds up using C functions such as getchar()! That alone tells me the book isn't worth the paper its printed on.

    Either that's not the complete code in the book, or the author doesn't know C++ well enough to teach it. Then again, if there is more code that allows you to print an array like this, I would argue that the author still doesn't know C++ well enough to teach it properly.

    The code suggests fundamental misunderstandings on the author's part.
    My best code is written with the delete key.
