First Project in C++
Example:
C++
#include <iostream> int main() { std::cout << "Welcome to C++"; return 0; }
This is a simple C++ program that prints the message “Welcome to C++” to the console.
- #include <iostream>: This line tells the compiler to include the header file
iostream
. This header file contains declarations for the standard input/output library. - int main(): This line defines the main function. The main function is the entry point for all C++ programs.
- std::cout << “Welcome to C++”;: This line prints the message “Welcome to C++” to the console using the
std::cout
object. - return 0;: This line returns the value 0 from the main function. This indicates that the program terminated successfully.
When you compile and run this program, the following output will be printed to the console:
Welcome to C++
This is a very simple example of a C++ program, but it illustrates some of the basic concepts of the language, such as header files, functions, and input/output.
