why a= new char [210]; but strlen(a)= 224??

[CharChen]

        char *bin;
        bin = new char [210];
	if(strlen(bin)!=210)
	{
//I used debug to detect the strlen(bin),it's 224. Not 210
		MessageBox (NULL,L"error!!",L"error!!",NULL);
	};

Why is that?

in debuger..the value of bin is

there's really something wrong with that..

because strlen() is looking for the terminating 0 while the content of bin is uninitialized. The result is undefined

i think you are lucky, 'cause when i try to do something similar i get an access violation runtime error.
if you're sure you don't want to initialize the array, try this:

char *a;
a = new char[210];
a[209] = '\0';
