I agree with you on that.
But the codes below works even if you input more than 10 characters?
Why?

#include <cstdio>
#include <cstring>
#include <iostream>
using namespace std;
int main()
{
char *str;
str = new char[10];
printf("Enter a string to reverse\n");
scanf("%s",str);
cout << strlen(str)<< endl;
system("pause");
return 0;
}

I don't know, it's not C!
Please post C++ questions to comp.lang.c++

<OT>
I don't see why would it work for more characters than you allocate.
