Initialization of all elements of an array to one default value in C++?

Question

C++ Notes: Array Initialization has a nice list over initialization of arrays. I have a

int array[100] = {-1};

expecting it to be full with

Answer 1

In the C++ programming language V4, Stroustrup recommends using vectors or valarrays over builtin arrays. With valarrary's, when you create them, you can init them to a specific value like:

valarray seven7s=(7777777,7);

To initialize an array 7 members long with "7777777".

This is a C++ way of implementing the answer using a C++ data structure instead of a "plain old C" array.

I switched to using the valarray as an attempt in my code to try to use C++'isms v. C'isms....
