Char type array

[Sava Mikalaèki]

Hi there!

My problem consists in this:
When I define an array of char type like this:
char a[]={'a','aa','aaa'};
I get a lot of warnings like
warning C4305: 'initializing' : truncation from 'const int' to 'char'
I've tryed to define the size of it (char a[10] ) but I get same warnings
every time.
What's wrong with this?
Poz,
Sava

char is a single charater. 'a' is a single character.
The constant 'aa' is an implementation defined int consant.
It is NOT a string literal. A string literal would be "".

char a[] is an array of (with this initialization) 3 characters.
It is not an array of strings.

If you want strings, do this:

#include <string>
std::string a[] = { "a", "aa", "aaa" };

In C/C++ 'aa' and 'aaa' are integer constants. The compiler already
explained the rest. You are trying to initialize members of 'char' array
with these constants, which results in truncation.

There's no way to say what else is wrong with this until you explain
what is that you are trying to do.
