Codeblocks hello world not working2/3/2024 #Having made the change, choose Build -> Build and run (F9 is a shortcut). #In the source code editor panel, modify the 'cout' line that you see, to say: #Here is a (sped up!) clip that shows how to use Code::Blocks on a PC (the steps would be similar on a Mac), to compile and run a program/sourcecode: ![]() Press F9, to watch the "source code get compiled, then executed". Click on Workspace -> HelloWorld -> Sources -> main.cpp to bring it up in CodeBlock's text editor. #Bring up Code::Blocks, create a new workspace (a container for a lot of 'project's), and within it (workspace), a new project (itself a container for a group of files that will together form a working program) called HelloWorld. Unzip what you downloaded, now you're ready to start learning C++!! Please download it from this link - PC users should get, and Mac users,. #We're going to use Code::Blocks, a very simple UI to do C++. #Next, let us do a 'soup to nuts' running of a C++ program, to get a hang of the workflow. #Again, our one-line program with Zen-like minimal syntax (no parantheses, no semi-colon) just directly ran, without compilation. Type the following into the big textarea in the middle, then press the 'Run' button at the top left. #Go to, where there's a browser-based 'REPL'. #As tiny as our program was (just one line!), it did not need to be compiled, it "just ran". ![]() Examine the source for the page you loaded :) #Here's a small example of using JavaScript. #* faster execution than interpreted code provides the programmer, better control of memory usage #* needs a compiler (program) to convert source code to an executable #* "all at once": code can't be run piece by piece #* an interactive interpreter is a 'REPL' (Read-Evaluate-Print-Loop) processor #* examples: JavaScript, Python, Perl, etc. #* an interpreter (program) processes the code, executes it #* 'lightweight', casual, inviting, "fun". #Even before we begin looking at C++, let's consider the two common ways of "running code": ![]() #In this lecture, we do a quick tour of C/C++'s features, starting from looking at interpretation vs compilation, and noting the language's various aspects (types, operators, flow control, etc.).
