std::string is pretty much just a pointer wrapped up in a class so you don't have to worry about new-ing and deleting a char buffer. 1234567 class string { private: char* data; public: string() : data(nullptr) {} // etc }; so by new-ing you are doing one more new, for the...

Program to interchange/swap two numbers using pointers in C++. To swap two numbers using pointers, we will first store the values in normal variables and declare two pointers to them.
as for p1++ I am guessing that is either a pointer to a char array or an iterator of a string. It is probably starting at the first character then when you increment it , it points to the next character. So basically what it is doing is looping through the strings and checking each...

Introduction cppsrc,vsVsProject Reread the code in Display 10.9 . Then, write a class TwoD that implements the two-dimensional dynamic array of double s using ideas from this display in its constructors. You should have a private member of type pointer to double to point to the dynamic arr...
