What are the advantages and disadvantages of using the make_unique function in C++?

The make_unique function in C++ creates an object in dynamic memory and returns a std::unique_ptr smart pointer to that object.

Advantages:

• Safe memory management: prevents memory leaks, as unique_ptr automatically deletes the object.
• Convenience: no need to explicitly write new and delete.
• Prevents errors with exceptions: the object is created and immediately wrapped in a unique_ptr, which prevents leaks if an exception is thrown.

Disadvantages:

• Requires C++14 support or higher (not available in C++11 standard).
• Slightly more overhead compared to raw pointers, but justified by safety.

Example usage:

#include <memory>

struct MyClass {
    int value;
    MyClass(int v) : value(v) {}
};

int main() {
    auto ptr = std::make_unique<MyClass>(42);
    // ptr will automatically free memory when it goes out of scope
}
