What is the name of the header file that contains the declaration of the malloc() function in C and C++?
531
The malloc() function in C++ allocates a block of uninitialized memory to a pointer. It is defined in the cstdlib header file.
h is a standard C header that declares among other things the malloc() , calloc() , free() functions. This is the header you should include. malloc. h is a non-standard header, found on many systems where it often defines additional functions specific to the malloc implementation used by that platform.
2) Declaring a static variable in a header means that each source file that includes it will have its own version of that variable rather than a single shared variable.
Syntax: ptr = (cast-type*) malloc(byte-size) For Example: ptr = (int*) malloc(100 * sizeof(int)); Since the size of int is 4 bytes, this statement will allocate 400 bytes of memory.
It's in stdlib.h (C) and cstdlib (C++).
In general, for such questions, just try to look on google: "c++ function". Most often the first hit will point to cplusplus.com for me containing a complete reference to the standard stuff.
