I'm learning C++ and win32 using Dev-C++.

I wonder if there is a build in Fn to get the size of a string?
eg: my string define as follow:
char mystring[] = "this is my question?"

Thanks.

Yah, to get the size of a string use:

(Toggle Plain Text)

int x;
x = strlen(stringName);

or

string mystring = "this is my question?"

int x = mystring.length();

BTW, in case you're interested, strlen can be defined as:

(Toggle Plain Text)

int strlen (char *str)
{
    for (int i = 0; *(str + i); i++);
    return i;
}

(Again, I think.)
