C++ STL set::clear() function: Here, we are going to learn about the clear() function of set in C++ STL (Standard Template Library).
<unordered_set> using namespace std; int main () { //create a unordered_set unordered_set<int> u_set = {1, 2, 3, 4, 5}; cout<<"Contents of the u_set before the clear operation are: "<<endl; for(int n : u_set){ cout<<n<<endl; } //using the clear() function u_set...

C++ STL中unordered_set的clear()函数 在C++ STL中,unordered_set是一种集合类型,它可以存储不重复的元素,并能够快速地完成元素的查找、插入和删除等操作。在实际应用中,我们可能需要清空unordered_set中存储的所有元素,此时就需要用到clear()函数了。 unordered_set
C++ vector clear() function❮ Vector Functions ExampleClear the contents of a vector:vector<string> cars = {"Volvo", "BMW", "Ford", "Mazda"}; cout << "Size before: " << cars.size() << "\n"; cars.clear(); cout << "Size after: " << cars.size() << "\n"; ...
clear()function resets the error state of the stream. Whenever there is an error in the stream, the error state is set toeofbit(end of file), and by usingclear(), we can reset it back togoodbit, saying there is no error. #include<bits/stdc++.h>using namespace std;intmain(){strin...
