Why for is a keyword but printf is not?

Question

Debojit Acharjee 455

If for is a function like prinft() then why printf() is not a keyword?

If 32 keywords are a part of the standard C library then why not printf() because printf() is a part of the header file stdio.h.

for is not a function. It is a statement. Being a keyword is how the parser know this.

printf is a function and not part of the language, only the standard library.
