Static array initialization In Cpp with examples: we have seen that static variable v0x1, 0x2, 0x3, 0x0, 0x5 (This is a somewhat academic question I know its not that hard to just use C arrays for this.) Like any other variable in C, an array starts out with an indeterminate value if you dont initialize it. The only difference is that unlike a simple variable, which contains only one undetermined value, an array starts out with a whole lot of unknown values Initialization.

Chapter 8 introduced the static const variable that allows you to define a constant value inside a class body. When initializing an object of array type, the initializer must be either a string literal (optionally enclosed in braces) or be a brace-enclosed list of initialized for array members: 1) string literal initializer for character and wide character arrays. in cpp file: const int a::SIZE 5 const char array[SIZE] "hello", "cruel","world","goodbye", "!" however, I did not find a way around the constant 10.C Class, Assigning values during Constructor initialization. 1.
