Why won't this reverse in the private member s?Code:#include<string.h> #include<iostream.h> const int max_len = 255; class string { public: void assign(const char* st) { strcpy(s, st); len = strlen(st); } int length() const { return len; } void print() const { cout << s << "\nLength: " << len << endl;} private: char s[max_len]; int len; reverse(); }; int main(void) { string one, two; char three[40] = {"My name is Charles."}; one.assign("My name is Alan."); two.assign(three); cout << three; cout << "\nLength: " << strlen(three) << endl; if (one.length() <= two.length()) one.print(); else two.print(); return 0; }
