Oct 28, 2024 pm 06:30 PMAdvantages of std::make_unique
Using std::make_unique to initialize std::unique_ptr has the following advantages:
Readability enhancement
- std::make_unique directly indicates that you intend to create a smart pointer, while new implies the creation of a raw pointer.
Type Safety
- std::make_unique enforces type safety, it automatically creates the correct std::unique_ptr based on the template type argument Example.
Exception Safety
- std::make_unique is exception safe, it will automatically free the allocated memory if the constructor throws an exception.
Efficiency
- std::make_unique is generally more efficient than using new because it avoids extra function calls and memory allocation operations.
Prevent memory leaks
- std::make_unique can prevent memory leaks because it automatically frees allocated memory even when the function throws an exception case.
Better than new
-
In general, using std::make_unique is better than using new to create smart pointers . Here are some situations where std::make_unique is recommended:
- When you need to create a simple std::unique_ptr instance.
- When you need to ensure exception safety.
- When you want to be more efficient.
Case in which std::make_unique is not suitable
- When you need to use a custom destructor, Don't use std::make_unique.
- Also do not use std::make_unique when you need to take a smart pointer from a raw pointer.

Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.

C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.

Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.

People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
