I'm a beginner learning C and I'm wondering whether it's worth investing the time. Even small projects can take hours because I'm dealing with memory, strings, compiler errors, undefined behavior, and easy-to-miss details such as the terminating NUL character. I also don't see as many job listings specifically asking for C compared with languages like Python or JavaScript, and some of these problems seem to be avoided by higher-level languages. Is C still valuable for careers or for becoming a better programmer, or would my time be better spent learning something else first?

Don’t choose a language only because someone says it is universally required. Choose based on what you want to build. C is especially worthwhile if you’re interested in embedded development, operating systems, compilers, graphics, or understanding computer internals. If you mainly want web development, automation, or data analysis, another language may get you productive sooner.
C teaches concepts that higher-level languages often hide: memory layout, pointers, data representation, compilation, system calls, and the costs of different operations. Even if you later work mostly in Python, JavaScript, or another language, that understanding can make you a stronger programmer and help you avoid inefficient code.
One small correction: when you write a quoted string such as "Hello", the compiler automatically stores a terminating NUL character at the end. The escape sequence n is a newline, not NUL. Missing terminators can happen when constructing character arrays manually, but they aren’t something you normally type into every string literal.
C deliberately gives you fewer safety checks and less built-in functionality. That means you write more code and have to manage details yourself, but it also gives you control and makes the machine’s behavior easier to study. The difficulty isn’t proof that the language is useless; it’s part of what you’re learning.
Yes, but the value depends on your goals. C is widely used in embedded systems, operating systems, performance-critical software, networking, and maintaining older systems. It may not be the fastest route to a general software job, but it is far from obsolete.
That said, you don’t need to master every corner of C before learning anything else. If your immediate goal is getting hired quickly, a language with more current entry-level roles may be a practical first choice, while C can remain part of your foundation.
