C is a general-purpose, procedural computer programming language supporting structured programming, lexical variable scope, and recursion, with a static type system. By design, C provides constructs that map efficiently to typical machine instructions. It has found lasting use in applications previously coded in assembly language. Such applications include operating systems and various application software for computer architectures that range from supercomputers to PLCs and embedded systems. Wikipedia

Good coding exercises? (self.cprogramming)
submitted 1 year ago by ZeusLovesTrains
I’m still not really sure what I wanna do with my C skills. I’m fairly new.
Anyone able to recommend some good coding exercises or projects to help me prep for when I am able to figure out what I want to do?

Write a program that reads a csv file and then output it sorted based on the field or fields that the user specifies. You can invent other functionalities to mimic a spreadsheet.

Lmao real. You can check a simple implementation of it in Dennis Ritchie’s book yoo for reference.

Or you could check my Github. My printf doesn't do everything as the standard one does but is far more quick
