Our first simple program will be simple, it's gooing to display Hello World! on your command line. To do this, we need to:
- Include the library that will allow us to print the message on the command line.
- As it is a standard library, we will need either to use 'std::' every time we use any function of the library or specify that we are using it, so the compiler accept it.
- Then we will create the main function stating "int main(){}". Our code will need to be in between the curly braces.
- Then, using the cout function we will write the 'Hello World!' message.
- Finally, the last line of the main function should be 'return 0'.
Also don't forget to end every line (except from the includes and the function-related lines) with a column ';'
After all this, if we run the program, the message should be printed!
E.g. :
#include <iostream>
using namespace std;
int main(){
cout << "Hello World!" << endl;
return 0;
}
