• Enable compiler warnings and treat them as errors. This helps catch potential issues early in the development process.

• Take advantage of C++11 move semantics to optimize resource management and performance, especially with temporary objects.

cppCopy codeclass MyClass {
public:
MyClass(MyClass&& other) noexcept : data(other.data) {
    other.data = nullptr; // Leave other in a valid state
}
private:
int* data;
};

• While it may seem convenient, this can lead to name clashes and confusion. Instead, use explicit namespaces to keep your code clear.

• When defining constructors, prefer initialization lists to initialize member variables. This can improve performance, especially for complex types.

cppCopy codeclass Example {
public:
Example(int value) : member(value) {} // Initialization list
private:
int member;
};

• Write small functions that do one thing well. This improves code readability, makes testing easier, and enhances maintainability.

• Take advantage of the STL (Standard Template Library). Use containers like std::vector, std::map, and algorithms (e.g., std::sort, std::find) to write more efficient and readable code.

• Ensure resources (memory, file handles, etc.) are tied to object lifetimes. Use constructors and destructors to manage resource allocation and deallocation automatically.

• Use const for variables that shouldn’t change and constexpr for values that can be computed at compile time. This improves readability and can optimize performance.

• Prefer smart pointers (std::unique_ptr, std::shared_ptr) over raw pointers to manage dynamic memory. This helps prevent memory leaks and makes ownership clearer.
