remove 函数可以用于删除 vector、list、deque 等 STL 容器中 的元素。它的使用非常简单,只需传入容器的起始和结束迭代器,以 及要删除的元素的值即可。例如: ```c++ vector<int> vec = {1, 2, 3, 4, 5}; vec.erase(remove(vec.begin(), vec.end(), 3), vec.end()); // 删除 vec 中的 3 ...
vector<int>ivec; inti; vector<int>::iterator it; for(i=0;i<5;++i) ivec.push_back(i); for(i=0;i<5;++i) ivec.push_back(i); //it = remove_if(ivec.begin(),ivec.end(),compare); it=remove(ivec.begin(),ivec.end(),3); ivec.erase(it,ivec.end()); for(vector<int>...
We can also remove a range of elements by passing first and last position in the erase function. Syntax: For removing a range of elements: vector_name.erase(iterator first, iterator last);Example: vector1={10, 20, 30, 40, 50, 60, 70, 80}, iterator_first=vector1.begin()+1, ...

After sorting and applying std::unique, instead of erasing duplicates, we employ the resize function to adjust the size of the vector directly.This results in a vector containing only the unique elements.myVector.resize(std::distance(myVector.begin(), last)); ...
Thelistclass has a more efficient member function version ofremove, which also relinks pointers. Example // alg_remove.cpp // compile with: /EHsc #include <vector> #include <algorithm> #include <iostream> int main( ) { using namespace std; vector <int> v1; vector <int>::iterator Iter...
In some cases, we may want to remove only a specific number of zero values from the vector. Here, we remove the first two zeros. clc clear n=[102030];indices=find(n==0,2);n(indices)=[];n In this case, the second argument of thefind()function is utilized to limit the number of...
C/C++ C++ 11 std::function和std::bind用法 2019-12-19 13:39 −std::bind() std::bind 主要用于绑定生成目标函数,一般用于生成的回调函数,cocos的回退函数都是通过std::bind和std::function实现的。两个点要明白:1.绑定全局或者静态函数比绑定成员函数... ...
