什么是最简单的解析算法可以解析C代码？

Does anyone know what the weakest family of widely-used parsing algorithms is that can parse C code? That is, is the C grammar LL(1), LR(0), LALR(1), etc.? I'm curious because as a side project I'm interested in writing a parser generator for one of these families and would like to ultimately be able to parse C code for another side project.Does anyone know what the weakest family of wid
