I think C out-evolved pascal. In the early days, both languages were a bit deficient when it came to meeting the user's needs, but C evolved more quickly. Wirth produced Modula-2 to overcome the limitations of Pascal, but it was too big a step, and the users didn't migrate. In contrast, the newer C compilers would still compile the older code, so you didn't get such a big hurdle.

I still miss some of the Pascal features, but I can't imagine going back. The modern code analysis tools cover some of the missing ground, so I can live without the Pascal nanny.
