I'm just starting out with C and have been wondering whether the time and frustration are worthwhile. Small mistakes, such as misunderstanding how strings and the terminating NUL character work, can lead to confusing bugs and hours of debugging. I also don't see many job listings specifically asking for C developers, and it seems like higher-level languages avoid many of these problems. Should I continue investing in C, either for career opportunities or to become a better programmer, or would another language be a more practical starting point?

Don't choose a language solely because it appears in the largest number of job listings. Pick based on the kind of work you want and the concepts you want to learn. C is a strong foundation, but if you are trying to reach employment as quickly as possible, consider learning a more commonly requested language alongside it and build a few complete projects.
The terminating NUL character is not something you normally add manually to a string literal—the compiler adds it automatically. For example, a literal such as "Hello" is stored with an extra zero byte at the end. The escape sequence n is a newline, not a NUL character. Many C problems come from using the language without understanding its model, so learning to debug those mistakes is part of the experience rather than evidence that the language has no value.
Even if you never get hired to write C full-time, it teaches concepts that higher-level languages often hide: memory, pointers, data representation, compilation, and the cost of different operations. That understanding can make you a stronger programmer in almost any language.
C is small and relatively quick to learn at the language level, but it provides fewer built-in conveniences than languages like Python. That means you write more infrastructure yourself and have to handle errors and memory carefully. The extra effort is worthwhile if you want to understand how software interacts with hardware; otherwise, it may not be the best first priority.
Yes, but the value depends on your goals. C is especially useful for embedded systems, operating systems, performance-sensitive software, and maintaining older systems. It isn't the language behind every new application, but it is far from obsolete and is unlikely to disappear.
You don't need C for every career path, though. If your immediate goal is getting into web development, automation, or data analysis, a language such as Python may lead to useful projects and job skills faster.
