Static memory allocation: space for the article is presented from the binary at compile-time; these objects have an extent (or life time) so long as the binary which consists of them is loaded into memory.
Separate tools such as Unix's lint utility were being made that (amid other factors) could look for regularity of perform use throughout many supply documents.
One example is, looking at clock twice will frequently generate two different values, Hence the optimizer experienced improved not optimize absent the second read On this code:

This causes the compiler to replace that line with the complete textual content of the stdio.h standard header, which contains declarations for traditional read the article enter and output capabilities for example printf.
