hello world program in c++

#include <iostream>

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

Explanation:

• #include <iostream>: This line includes the input/output stream library, which allows input and output operations to be performed in the program.

• int main() { }: This is the main function where the execution of the program begins. In C++, every program must have a main function. int specifies that the function returns an integer value.

• std::cout << "Hello, World!";: std::cout is used to output data to the console. The << operator is used to insert the string "Hello, World!" into the standard output stream.

• return 0;: This statement signifies the end of the main function and returns an integer value (0) to the operating system, indicating that the program executed successfully.
