Hello,
Is there any limitation for the length of array variables in C++?
Can I specify the length as wanted or is there any limitation for the array length? What should be the array length, if the length is not known.
wchar_t commandString[10000];
Cheers
In C++, best NOT to use C type strings.
Use C++ string instead.
The C++ string will size itself to be the right size to hold your string and can be as big as available memory for a C++ string
See:

and:

So wchar_t is a C string?
I thought it was C++ string?
Oops ... sorry for double post :(

Hi,
If you include the header limits in your program you can get the limit of wchar_t max to be 65535 and lowest to be 0. Something like thus:
#include <iostream>
#include <limits>
int main() {
std::cout << "lower limit for wchar_t: "
<< std::numeric_limits<wchar_t>::min()
<< "\nupper limit for wchar_t: "
<< std::numeric_limits<wchar_t>::max()
<< std::endl;
return 0;
}
Of course, if your intension is to use string value in c++ is better you are using std::string not c string like it was pointed out previously.
Hope this helps.
And if you need wide chars in your C++ string use std::wstring instead of std::string. All that wchar_t is is a wide (2 byte) character that can contain unicode characters. It is a common C type for systems that have to support international languages.
