field construct is so common that C includes a shortcut for it: The arrow operator allows you to write ptr->field in place of (*ptr).field. Thus, the following definition is equivalent.#include <math.h> double distToOrigin(struct Point *p) { return sqrt(p->x * p->x + p->y *...
Watch the video below to learn the fundamentals of C: Definition of Pointer in C Every variable is stored in some memory location, and that memory location has an address. A pointer is a variable that stores the memory address of variables, functions, or other pointers. A pointer is a ...
Pointers provide a way to manipulate data directly in memory, leading to efficient and powerful programming techniques. Definition and Usage A pointer in C is declared by specifying a data type followed by an asterisk (*) before the variable name. The data type indicates the type of data the...

A function can take a pointer to any data type, as argument and can return a pointer to any data type. For example, the function definition double *maxp(double *xp, double *yp) { return *xp >= *yp ? x; } specifies that the function maxp() return a pointer to a double variable...
