First Program: Hello World

Introduction to C++ Programming
First Program: Hello World

● This is the first program that most people write when they are
learning a new programming language.
● It is used to verify the installation of the compiler and the
development environment.

,Code Example


#include <iostream>


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


● The output of the program is:
Hello, World!



Types and Variables
● In C++, there are different types of variables, such as int,
float, double, char, etc.
● Variables must be declared before being used.


Arrays
● An array is a collection of elements of the same type.
● The elements are stored in contiguous memory locations.

, Strings
● A string is a sequence of characters.
● In C++, strings can be implemented using the std::string
class.


Control Statements: If-Else, For, and While Loops

If-Else

● The if statement is used to execute a block of code if a
condition is true.
● The else statement is used to execute a block of code if the
condition is false.


Code Example


#include <iostream>


int main() {
int number = 10;


if (number > 5) {
