class myString new programmer

class mystring {

public:

mystring(const char x[])
    : capacity(1024)
{
    for (int i = 0; i < capacity; ++i)
    {
        if (x[i] == '\0') break;
        s[i] = x[i];
        length++;
    }
}
mystring()
    : capacity(1024), s('\0'), length(0)
{}

//etc...

private:

const int capacity;
char s[1024];
int length;

};

I'm getting this error:

In file included from main.cpp:19:0: mystring.h: In constructor ‘mystring::mystring()’: mystring.h:21:44: error: incompatible types in assignment of ‘char’ to ‘char [1024]’ : capacity(1024), s('\0'), length(0) I don't under stand what's going on. I'm a bit new to constructors. Thanks in advance!
