Puede que C sea un lenguaje relativamente sencillo, pero el estándar C tiene unas 700 páginas, así que, a menos que quieras dedicar tu vida a estudiarlo, es importante saber qué partes se pueden ignorar.
Podemos empezar con dígrafos y trígrafos. Si a tu teclado le faltan las teclas { y }, puedes utilizar <% y %> en su lugar (como int main() <% … %>). Esto era relevante en los años 90, cuando los teclados de todo el mundo seguían costumbres diversas, pero hoy en día es difícil encontrar un teclado en cualquier parte al que le falten las llaves rizadas. Los equivalentes trigráficos de C99 y C11 §5.2.1.1(1), ??< y ??>, son tan inútiles que los autores de gcc y clang no se molestaron en implementar código para analizarlos.
Los rincones oscuros del lenguaje, como los trígrafos, son fáciles de ignorar, porque nadie los menciona.
