You'll be using Notepad to create a basic C++ program that displays "Hello World!" when run. Type in // followed by your program's title (e.g., "My first program"). Any text in a line that's typed after two slash marks will show up as plain text (e.g., not part of the program). For example: to entitle your program "Program 1", you'd type //Program 1 into Notepad. Type #include <iostream> into Notepad, then press ↵ Enter. This command instructs C++ to run the following lines of code as a program. Type int main () into Notepad, then press ↵ Enter. Type into Notepad. This closes the program's execution phase. m. Make sure that you use the .cpp extension when doing so. Once you've saved the program, you should be able to run it in your preferred C++ compiler.
