The OP said that using a spreadsheet program can be messy and prone to mistakes, and implied that there could exist alternative approaches. The OP never said a bug in Excel was responsible for the mistake or blamed Microsoft for corrupting the calculation. In the same sense, one could say manual memory management in C can be messy and prone to mistakes, it doesn't mean that one believes C should never be used in any circumstance, and it doesn't mean one's trying to blame the C complier, libc or Dennis Ritchie for corrupting one's program. Hypothetically, if someone writes the following reply. > The C programming language, whether you like it or loathe it, is in such wide use around the world that a NULL pointer dereference would have been noticed a very long time ago. I could believe that there are still many lurking libc bugs with obscure corner cases, but I would bet the memory corruptions were solely due to your own failures. It would completely miss the point.
