How do malloc() and free() work? http://stackoverflow.com/questions/1119134/how-do-malloc-and-free-work reason of course is that the OS can only handle memory chunks that are of a specific size and alignment. To be specific Normally.. The free block list is just a circular list of memory chunks which have of course some admin data in the beginning. This.. to this standard behaviour for example for small chunks of memory . But since malloc and free must be so universal the..

Why is reading lines from stdin much slower in C++ than Python? http://stackoverflow.com/questions/9371238/why-is-reading-lines-from-stdin-much-slower-in-c-than-python uses plain C read within the safe read.c wrapper to read chunks of 16k bytes at a time and count new lines. Here's a python.. one character at a time the stream will be read in larger chunks. This reduces the number of system calls which are typically..
