For example, write a program that asks the user for two numbers and prints their sum.

#include <iostream>

int main() {
    int num1, num2, sum;

    std::cout << "Enter the first number: ";
    std::cin >> num1;

    std::cout << "Enter the second number: ";
    std::cin >> num2;

    sum = num1 + num2;

    std::cout << "The sum is: " << sum << std::endl;

    return 0;
}

3.3. Diving Deeper: Intermediate Concepts

4. Transitioning from Java to C++: Key Differences and Similarities

How long to learn C++ if already fluent in Java? If you’re already fluent in Java, you can grasp the basics of C++ relatively quickly, often in just a few days, due to the languages’ similar syntax and object-oriented principles. However, mastering C++-specific concepts like memory management and pointers may take several weeks. LEARNS.EDU.VN provides tailored resources for Java developers transitioning to C++, highlighting the key differences and similarities to accelerate your learning process.

4.1. Leveraging Your Java Knowledge

Java and C++ share several similarities, making the transition easier:

Syntax: Both languages have similar syntax for basic operations, such as variable declarations, loops, and conditional statements.
Object-Oriented Programming: Both languages support OOP principles like encapsulation, inheritance, and polymorphism.
Data Types: Both languages have similar data types, such as int, float, char, and boolean.

4.2. Key Differences to Watch Out For

Despite the similarities, there are significant differences between Java and C++:

Memory Management: Java uses automatic garbage collection, while C++ requires manual memory management using new and delete.
Pointers: C++ uses pointers to directly manipulate memory addresses, while Java uses references.
Multiple Inheritance: C++ supports multiple inheritance, while Java only supports single inheritance.
Operator Overloading: C++ allows operator overloading, while Java does not.
Header Files: C++ uses header files to declare functions and classes, while Java uses packages.

4.3. Memory Management: The Biggest Hurdle

Memory management is the most significant difference between Java and C++. In Java, the garbage collector automatically reclaims memory that is no longer being used. In C++, you must manually allocate and deallocate memory using new and delete.

Failing to deallocate memory can lead to memory leaks, which can cause your program to crash or run slowly. Mastering memory management is crucial for becoming a proficient C++ programmer.

4.4. Code Example: Memory Allocation in C++

Here’s an example of how to allocate and deallocate memory in C++:

#include <iostream>

int main() {
    int* ptr = new int; // Allocate memory for an integer

    *ptr = 10; // Assign a value to the allocated memory

    std::cout << "Value: " << *ptr << std::endl;

    delete ptr; // Deallocate the memory

    ptr = nullptr; // Set the pointer to null to prevent dangling pointers

    return 0;
}

In this example, new int allocates memory for an integer, and delete ptr deallocates the memory. Setting ptr to nullptr after deallocation prevents dangling pointers, which can cause undefined behavior.
