The C++ std::ios::swap() function is used to swap the state of two ios objects, exchanging their internal states, such as formatting flags, buffer pointers, and other attributes.std::ios::swap() function is employed to maintain stream consistency or optimize performance in input/output ...
In the below example, we see how to swap two user-defined objects usingstd::swap()function. Here we have defined a student class as we see how swap swaps the content between them. #include <bits/stdc++.h>usingnamespacestd;classstudent{public:introll; string name;intmarks; student() {...
