When I was learning C in the 80's, I used to write programs to prove or disprove if a number is prime. Specifically the Lucas Lehmer test.
Easy to do in C. Re-writing in 8051 assembler will make you a real programmer. Moreso if you then re-write code to get your graphics card to do it using ultrafast VRAM.
Dissassembling programs is also good practise. Compile a program to multiply two numbers, go and look at the generated code and try to work out what's going on.
I personally always find assembly programming more challenging. Getting a floating point divide to work is easy. Not in 128bytes of stack in 512bytes of reserved code space it isn't.
