Calculate Sum of Numbers in Array

Even without smart pointers, you can manage memory safely in C++ using the RAII pattern. This approach:

• Prevents memory leaks.
• Simplifies exception handling.
• Keeps your code clean and maintainable.

class Deep {
public:
    int* data;

    Deep(int val) {
        data = new int(val);
    }

    // Copy constructor for deep copy
    Deep(const Deep& other) {
        data = new int(*other.data);
    }

    // Assignment operator for deep copy
    Deep& operator=(const Deep& other) {
        if (this != &other) {
            delete data;
            data = new int(*other.data);
        }
        return *this;
    }

    ~Deep() {
        delete data;
    }
};

If your class handles dynamic memory:

We’ll implement a recursive-descent parser that constructs an Abstract Syntax Tree (AST) from tokens. Our grammar is defined with standard operator precedence:

expression → term ((‘+’ | ‘-’) term)*
term       → factor ((‘*’ | ‘/’) factor)*
factor     → Number | ‘(’ expression ‘)’
