I know it sounds kind of subjective, but I want to implement basic library functions in C in order to gain better understanding in C (mostly in pointers) and improve my skills, since I’m only a beginner (in C & programming in general).
I also find it useful since you get to understand better what happens behind the scenes and how those basic functions work.
Which basic C library functions can I implement? I’m looking for simple ones like strcpy, atoi, strstr that are not too complicated (I’m only a beginner) but still require some thinking.
Strings function are always challanging (and required). Try split a string to tokens, join strings, replace string in strings. Believe me, after that not only you will be a better C programmer, you will also appreciate open source libraries! (and C++ STL..)
Good luck!
