memleak in map

Code:

---

#include <iostream>
#include <map>
using namespace std;
 
int main()
{
        map < int , string > sampMap;
        map < int , string > sampMap1;
        sampMap[1] = "Adams";
        sampMap[2] = "Peter";
        map < int , map< int , string >> tempMap;
        tempMap[1] = sampMap;
        sampMap1 = tempMap[1];
        sampMap1[3] = "Thomson";
        tempMap[1] = sampMap1;
}

---

Will this program cause any memory leak?
As we are assigning( over writing ) sampMap1 to tempMap[1], will the tempMap loose the reference of sampMap and produce any memory leak?

No.

Memory leaks can only be created when allocating memory from the heap. Since you don´t do that and map is assumed not to create any leaks, there will be no memory leaks.

The map class and the string class automatically free the memory they use.

Thank U Guys. :)
