Add map data

Add map data

1      // add data in six ways 
2      mp.insert ({ 0 , " Map ZERO " }); // Use} { 
. 3      mp.insert (pair < int , String > ( 1 , " Map One " )); / / use pair 
. 4      mp.insert (the make_pair ( 2 , " Map TWO " )); // use the make_pair 
. 5      mp.insert (the make_pair < int , String > ( . 3 , " Map Three " ));
. 6      mp.insert (Map < int , String > :: the value_type ( . 4 , " Map Four " )); // Use the value_type 
. 7      MP [ . 5 ] = " Map Five " ; // with the key, the value of direct assignment

Test code:

 1 #include<bits/stdc++.h>
 2 using namespace std;
 3 void show(map<int,string>& mp){
 4     map<int,string>::iterator iter=mp.begin();
 5     while(iter!=mp.end()){
 6         cout<<iter->first<<" "<<iter->second<<endl;
 7         iter++;
 8     }
 9 }
10 int main()
11 {
12     //Configured to Map 
13 is      Map < int , String > MP; // Construct a Map
 14  
15      // add data in six ways 
16      mp.insert ({ 0 , " Map ZERO " }); // Use} { 
. 17      mp.insert (pair < int , String > ( . 1 , " Map One " )); // use pair 
18 is      mp.insert (the make_pair ( 2 , " Map TWO " )); // use the make_pair 
. 19     mp.insert (the make_pair < int , String > ( . 3 , " Map Three " ));
 20 is      mp.insert (Map < int , String > :: the value_type ( . 4 , " Map Four " )); // Use the value_type 
21 is      MP [ . 5 ] = " Map Five " ; // directly with the key, value assignment 
22 is  
23 is  
24  
25      Show (MP); // output Map 
26 is      return  0 ;
 27  }

operation result:

1 0 map zero
2 1 map one
3 2 map two
4 3 map three
5 4 map four
6 5 map five
