What does the C++ standard state the size of int, long type to be?
...ng and pointer are all 32-bit quantities.
For 64-bit systems, the primary Unix 'de facto' standard is LP64 — long and pointer are 64-bit (but int is 32-bit). The Windows 64-bit standard is LLP64 — long long and pointer are 64-bit (but long and int are both 32-bit).
At one time, some Unix syst...

...d then the HOME environment variables. Failing that, it uses getpwuid() on UNIX-like systems (which returns the home dir

How does grep run so fast?
...ally looks at (and it skips many
bytes entirely).
GNU grep uses raw Unix input system calls and avoids copying data
after reading it. Moreover, GNU grep AVOIDS BREAKING THE INPUT INTO

several times, because to find the ne...
Why does the order in which libraries are linked sometimes cause errors in GCC?
