stl list 删除元素

## list.remove()和list.remove\_if()函数 **(**list.remove() and list.remove\_if() functions**)** ##

remove() function is used to remove all occurrences of a given element from the list and function remove\_if() is used to remove set of some specific elements from the list.

remove()函数用于从列表中删除所有出现的给定元素，而remove\_if()函数用于从列表中删除某些特定元素的集合。

**Example:**

**例：**

List elements are
        11
        22
        33
        44
        55
        11
        22
    
        Element to remove: 11
    
        List element after removing 11
        22
        33
        44
        55
        22
    
        Condition to remove some specific elements: all ODD numbers
        List element after removing all ODD numbers
        22
        44
        22

**Program:**

**程序：**

#include <iostream>
    #include <list>
    using namespace std;
    
    int main() 
    {
        
    	//declaring a list 
    	list<int> iList = {
        11, 22, 33, 44, 55, 11, 22};
    	//declaring iterator to the list
    	list<int>::iterator l_iter;
    
    	//printing list elements
    	cout<<"List elements are"<<endl;
    	for (l_iter = iList.begin(); l_iter != iList.end(); l_iter++)
    		cout<< *l_iter<<endl;
    
    	//remove 11 from the List
    	iList.remove(11);
    	cout<<"List elements after removing 11"<<endl;
    	for (l_iter = iList.begin(); l_iter != iList.end(); l_iter++)
    		cout<< *l_iter<<endl;
    
    	//remove all ODD numbers
    	iList.remove_if([](int n){return (n%2!=0); });
    	cout<<"List elements after removing all ODD numbers"<<endl;
    	for (l_iter = iList.begin(); l_iter != iList.end(); l_iter++)
    		cout<< *l_iter<<endl;
    
    	return 0;
    }
