uint32_t vs int as a convention for everyday programming

Question

When should one use the datatypes from stdint.h? Is it right to always use as a convention them? What was the purpose of the design of nonspecific size types like int and s

Answer 1

No, I would say it's never a good idea to use those for general-purpose programming.

If you really care about number of bits, then go ahead and use them but for most general use you don't care so then use the general types. The general types might be faster, and they are certainly easier to read and write.
