Tinycc on NaCl
What is this? This is an experimental port of tinycc. You can run C source code on NaCl, which means, you can run C programs on your browser without interaction with servers. Note that the development is not completed at all and you may see weird errors even for simple programs. You can find the source code and documents from my github repository To try this, you might need Chrome 14 or later and
A Guide to Undefined Behavior in C and C++, Part 1 – Embedded in Academia
Also see Part 2 and Part 3. Programming languages typically make a distinction between normal program actions and erroneous actions. For Turing-complete languages we cannot reliably decide offline whether a program has the potential to execute an error; we have to just run it and see. In a safe programming language, errors are trapped as they happen. Java, for example, is largely safe via its exce
