c++ map<string,string> 如何赋值

您可以使用以下方法为map<string,string>赋值：

1. 逐个插入键值对

map<string, string> myMap;
myMap.insert(pair<string,string>("key1", "value1"));
myMap.insert(pair<string,string>("key2", "value2"));

2. 利用初始化列表

map<string, string> myMap = { {"key1", "value1"}, {"key2", "value2"} };

3. 利用迭代器遍历赋值

map<string, string> myMap;
vector<pair<string, string>> vec = { {"key1", "value1"}, {"key2", "value2"} };
for (auto iter = vec.begin(); iter != vec.end(); iter++) {
    myMap.insert(*iter);
}
