For this, we usetie()function, which unpacks the tuple. Below is the example of using tuple in C++. #include <bits/stdc++.h>usingnamespacestd;intmain() {//define a tuple of <roll,marks,name>tuple<int,int, string>student;//create the pairstudent=make_tuple(1,80,"XYZ");//extract...

returnmake_tuple(U, S, V); }; The above use is analogous to standardpairs. When the function is called, there are two ways to access the results. First, you can store the result to a tuple object and access the elements with special access functions (get): ...
如果需要返回三个或更多的返回值,则可以基于tuple(元组)这一数据结构,用类似于上述操作的方法来实现。...举一个例子,假如我们想通过一个函数返回三个返回值,就需要将前述代码中函数的类型定义为tuple,将make_pair()函数更改为make_tuple(),且在调用函数时首先将返回值赋给一个 38810 C++11中的tuple...
