+# emplace_hint
+
+**Description :** 
+  * Inserts the key and its element in the unordered_map with a given hint. The hint provided does not affect the position to be entered. It inserts in the same order         which is followed by the container. 
+  * Only inserts unique key and avoids creating object for exisitng key.
+
+**Example** :
+
+```cpp
+#include <iostream>
+#include<string>
+#include<unordered_map>
+
+using namespace std;
+
+
+int main() {
+  
+    // initialize unordered_map container
+    unordered_map<int, string> mp;
+  
+    // inserting elements in random order
+    mp.emplace_hint(mp.begin(),3,"three");
+    mp.emplace_hint(mp.begin(),1,"one");
+    mp.emplace_hint(mp.begin(),2,"two");
+
+        
+    // printing the map elements 
+    cout<<"The unordered_map elements are:"<<endl;
+    cout<<"key\telement"<<endl;
+    
+    for(auto itr = mp.begin(); itr!=mp.end(); itr++){
+        cout<<itr->first<<"\t";
+        cout<<itr->second<<endl;    
+    }
+    
+    return 1;
+}
+```
