smart pointers in c++ code example

Example 1: c++ make shared_ptr

#include <memory>
std::shared_ptr<int> foo = std::make_shared<int> (10);

Example 2: c++ smartpointer

#include <memory>
 
void my_func()
{
    std::unique_ptr<int> valuePtr(new int(15));
    int x = 45;
    // ...
    if (x == 45)
        return;   // no memory leak anymore!
    // ...
}
 
int main()
{
}
