How Online C++ Compiler Works?
Here are the step-by-step instructions on how the C++ compiler works:
- Preprocessing: The preprocessing stage handles unusual code sections that include both #include and #define statements to prepare the code.
- Compilation: The compilation process checks the written code while transforming it into the final assembly language format.
- Assembly: It changes the assembly code to machine code that the computer can understand.
- Linking: During this stage, the compiler combines all files including code and libraries into a complete final program.
Practice on Online C++ Compiler
The online C++ compiler is a great tool for working on small projects. You can easily run and test your code just by using a browser. Let’s start by writing a simple C++ program using Intellipaat’s online C++ compiler and then we will move forward to C++ concepts.
Create Your First C++ Program in an Online Compiler
Let’s see step-by-step how you can write and run your C++ code in an online compiler:
Step 1: Open the Intellipaat’s online C++ compiler.
Step 2: Once open, type the following code in the editor.
#include <iostream>
int main() {
std::cout << "Hi, This is Intellipaat!" << std::endl;
return 0;
}
Step 3: Click on the ‘Run’ button to execute your program.
Step 4: You will get the following output:
What is C++?
C++ is an advanced programming language created by Bjarne Stroustrup in 1979 and it’s an extension of the C language. It introduced new features like Object Oriented Programming (OOP), pointers, and memory management which are used to create different applications like games and operating systems.
Features of C++
The key features of the C++ language are as follows:
- Object-oriented: C++ supports classes, inheritance, and polymorphism.
- Efficient: It is very fast and efficient for the tasks that need good performance.
- Low-level control: C++ gives you access to direct memory management with the help of pointers.
- Multithreading: You can do multiple tasks at the same time very easily.
- Exception handling: C++ can easily manage errors.
- Rich library: C++ has some big libraries like Standard Template Library (STL) to help you build your projects easily and fast.
C++ Syntax
C++ is a great choice for creating web apps but you must use proper syntax to write error-free code. Here are some important syntax elements that every developer should know about when writing code in C++ language:
Loops in C++
Loops are a very important concept in C++ that helps you repeat actions in your code. There are mainly 3 types of loops in C++: for loop, while loop, and do-while loop. Let’s see what they do:
1. For loop
For loop in C++ allows you to repeat the code for every item in the list.
Example:
int main() {
for (int i = 1; i <= 3; i++) {
cout << "User: " << i << endl;
}
Output:
2. While loop
While loop in C++ repeats the statements based on a condition. It allows you to repeat the code until the condition is true. We use a while loop when we don’t know the number of loop cycles.
Example:
int main() {
int i = 1;
while (i <= 3) {
cout << "User: " << i << endl;
i++;
}
Output:
3. Do-while loop
Do-while loop also allows you to repeat the code until the condition is true. But it is mostly used when you need to run the loop at least once.
Example:
int main() {
int i = 1;
do {
cout << "User: " << i << endl;
i++;
} while (i <= 3);
Output:
Conditional Statements in C++
Conditional Statements in C++ are really important programming constructs that help you make decisions based on the conditions.
1. If-else statement
If-else statement in C++ is used when you put a condition in the code and if the condition is met then the code in the ‘if’ block will be executed otherwise the code in the ‘else’ block will be executed.
Example:
int main() {
int num = 5;
if (num % 2 == 0) {
cout << "The number is even." << endl;
} else {
cout << "The number is odd." << endl;
}
Output:
2. Switch statement
The switch statement in C++ is similar to the ‘if-else’ statement. It is used when you have multiple conditions to check and only a single block of code will be executed depending on the value of the variable.
Example:
int main() {
int a = 8, b = 5;
if (a > b) {
cout << "The larger number is: " << a << endl;
} else {
cout << "The larger number is: " << b << endl;
}
Output:
Functions in C++
Functions are like a block of code that performs a specific task. They are reusable codes and can only be used when you call them. Function in C++ helps you to break your code into small parts which makes it easy to read.
Syntax:
return_type function_name(parameters) {
// Code
return value;
}
To declare a function:
return_type function_name(parameters);
To call a function:
function_name (parameters)
Classes and Objects
A class is like a blueprint that contains the data and functions of the object. An object is an instance of a class. It is a real-world object that is used in the class.
Example: In this example, we have a class ‘Intellipaat’ and an object ‘Intelli1’, and we will print the title of the book using class and object.
#include <iostream>
using namespace std;
class Intellipaat {
public:
string title;
void showTitle() {
cout << "Title of the Book: " << title << endl;
}
};
int main() {
Intellipaat Intelli1;
Intelli1.title = "C++ Programming";
Intelli1.showTitle();
return 0;
}
Output:
Inheritance in C++
Inheritance is one of the most important features of OOP which allows a class to inherit the properties of another class. It means a class can use the code of another class.
Types of Inheritance
There are 5 types of inheritance in C++:
- Single Inheritance: When a derived class inherits the properties from one base class.
- Multiple Inheritance: When a derived class inherits the properties from multiple base classes.
- Multilevel Inheritance: When a derived class inherits the properties from another derived class.
- Hierarchical Inheritance: When the multiple derived classes inherit the properties from a single base class.
- Hybrid Inheritance: It is a combination of two or more than two inheritances.
Basic Syntax of the Inheritance
class BaseClass {
public:
void baseFunction() {
std::cout << "Base class function" << std::endl;
}
};
class DerivedClass : public BaseClass {
public:
void derivedFunction() {
std::cout << "Derived class function" << std::endl;
}
};
