DescriptionPortabilitycalloc allocates space for an array of nmemb objects, each of whose size is size. Thespace is initialized to all zero bits.calloc returns a null pointer if the space for the array of object cannot be allocated fromfree memory; if space for the array can be allocated, calloc returns a pointer to the startof the allocated space.calloc conforms to ISO/IEC 9899:1990 (C90) and ISO/IEC 9899:1999 (C99).divSynopsisDescription#include div_t div(int numer, int denom);div computes numer / denom and numer % denom in a single operation.div returns a structure of type div_t (page 298) comprising both the quotient and theremainder. The structures contain the members quot (the quotient) and rem (theremainder), each of which has the same type as the arguments numer and denom. Ifeither part of the result cannot be represented, the behavior is undefined.Portabilitydiv conforms to ISO/IEC 9899:1990 (C90) and ISO/IEC 9899:1999 (C99).See also div_t (page 298)div_tSynopsis#include typedef struct {int quot;int rem;} div_t;Description div_t stores the quotient and remainder returned by div (page 298).Portabilitydiv_t conforms to ISO/IEC 9899:1990 (C90) and ISO/IEC 9899:1999 (C99).See also div (page 298)freeSynopsisDescription#include void free(void *ptr);free causes the space pointed to by ptr to be deallocated, that is, made available forfurther allocation. If ptr is a null pointer, no action occurs.298 Chapter 28 Standard C Library Reference
