C++ Online Compiler: Code, Compile, and Debug C++ Online

Introduction to C++ Language

C++ is a powerful, high-performance programming language widely used for system software, game development, competitive programming, and large-scale applications. Created as an extension of the C language, it introduced object-oriented programming while retaining C's efficiency. C++ continues to be a cornerstone of programming, offering versatility and control over hardware.

History of C++ Language

  • Development and Inception: C++ was created by Bjarne Stroustrup in 1979 at Bell Labs as an enhancement to the C language, initially named “C with Classes.”
  • First Release: The first version of C++ was released in 1985, introducing object-oriented programming concepts.
  • Standardization: C++ was standardized by ISO in 1998 (C++98). Subsequent updates like C++11, C++14, C++17, and C++20 introduced modern features, making the language more expressive and efficient.

What Kind of Language is C++?

  • Object-Oriented Language: Supports features like classes, inheritance, polymorphism, and encapsulation.
  • High-Level and Low-Level Features: Combines low-level capabilities like memory manipulation with high-level abstractions for ease of development.
  • Compiled Language: C++ code is translated to machine code using a compiler, ensuring optimal performance.

Key Features of C++ Language

  1. Object-Oriented Programming: Facilitates modular design and code reuse through classes and objects.
  2. Performance: C++ delivers high performance, making it ideal for performance-critical applications like gaming engines and real-time systems.
  3. Portability: Code can run on multiple platforms with minimal modifications.
  4. Standard Template Library (STL): Provides pre-built classes and functions for common data structures (e.g., vectors, maps) and algorithms.
  5. Memory Management: Offers manual control over memory using pointers, new, and delete.

Why Learn C++?

  • Versatility: C++ is used in systems programming, game development, competitive programming, and more.
  • Foundation for Advanced Programming: Learning C++ builds a solid foundation for understanding advanced programming concepts and other languages like Python and Java.
  • Widely Used in Industry: Applications like Adobe Photoshop, Google Chrome, and major game engines like Unreal are built using C++.
  • Competitive Programming: C++ is a preferred choice for competitive programming due to its STL and execution speed.

C++ Syntax and Tutorial

Here’s a comprehensive tutorial covering all the essential topics, from basic to advanced, with examples.

1. Basic Syntax

Hello World Program

#include <iostream>using namespace std;

int main() {
    cout << "Hello, World!" << endl;
    return 0;
}

2. Variables and Data Types

C++ supports various data types, including int, float, double, char, and bool.

int age = 25;
float pi = 3.14;
char grade = 'A';
bool isEligible = true;

3. Operators

Arithmetic Operators

int sum = 10 + 5;
int product = 10 * 5;

Relational Operators

if (a > b) {
    cout << "a is greater";
}

Logical Operators

if (x > 5 && y < 10) {
    cout << "Condition met";
}

4. Control Structures

If-Else Statements

if (age >= 18) {
    cout << "You are an adult.";
} else {
    cout << "You are a minor.";
}

Loops

// For Loop
for (int i = 0; i < 5; i++) {
    cout << i << endl;
}

// While Loop
int count = 0;
while (count < 5) {
    cout << count << endl;
    count++;
}

5. Functions

Function Declaration and Definition

int add(int a, int b) {
    return a + b;
}

int main() {
    cout << add(5, 10);
    return 0;
}

Function Overloading

int multiply(int a, int b) { return a * b; }
double multiply(double a, double b) { return a * b; }

6. Object-Oriented Programming

Classes and Objects

class Car {
public:
    string brand;
    int year;

    void displayInfo() {
        cout << brand << " - " << year << endl;
    }
};

int main() {
    Car car1;
    car1.brand = "Toyota";
    car1.year = 2020;
    car1.displayInfo();
    return 0;
}

Inheritance

class Vehicle {
public:
    string type;
};

class Car : public Vehicle {
public:
    string brand;
};

7. Advanced Topics

Pointers

int a = 10;
int *ptr = &a;
cout << "Value of a: " << *ptr;

STL Example

#include <vector>#include <iostream>using namespace std;

int main() {
    vector<int> nums = {1, 2, 3};
    nums.push_back(4);
    for (int num : nums) {
        cout << num << endl;
    }
    return 0;
}
