3、从set中查找和读取元素 从set中查找同样可以使用count()函数和find()函数,两者的区别在之前的map中已经总结。 例如: 代码语言:javascript 代码运行次数:0 复制Cloud Studio 代码运行 #include <stdio.h> #include <vector> #include <set> using namespace std; int main(){ vector<int> v; for (int ...
i));}if(mp.count(0)){printf("yes!\n");}else{printf("no!\n");}map<int,int>::iterator it_find;it_find=mp.find(0);if(it_find!=mp.end()){it_find->second=20;}else{printf("no!\n");}map<int,int>::iterator it;for(it=mp....
