memleak in map

[adapanaidu]

#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.
