C++ STL之min_element()与max_element（）（取容器中的最大最小值）

min_element()和max_element

头文件：#include<algorithm>

作用：返回容器中最小值和最大值。max_element(first,end,cmp);其中cmp为可选择参数!

 

闲言少叙，上代码，一看就懂：

#include<iostream>  
#include<algorithm>  
using namespace std;  
bool cmp(int a,int b)  
{  
      return a<b;  
}  
int main()  
{  
      int num[]={2,3,1,6,4,5};  
      cout<<"最小值是 "<<*min_element(num,num+6)<<endl;  
      cout<<"最大值是 "<<*max_element(num,num+6)<<endl;  
      cout<<"最小值是 "<<*min_element(num,num+6,cmp)<<endl;  
      cout<<"最大值是 "<<*max_element(num,num+6,cmp)<<endl;  
      return 0;   
}
