WebA pointer is a variable that stores the memory address of another variable as its value. A pointer variable points to a data type (like int) of the same type, and is created with the … WebFor example, int *int_ptr ### int_ptr is a pointer to data of type integer char *ch_ptr ### ch_ptr is a pointer to data of type character double *db_ptr ### db_ptr is a pointer to data of type double. Note: The size of any pointer in C is same as the size of an unsigned integer. Hence it is Architecture dependent.

WebPointer arithmetic is automatically scaled by the size of the pointed-to data type. Pointers are used for many purposes in C. Text strings are commonly manipulated using pointers into arrays of characters. Dynamic memory allocation is performed using pointers; the result of a malloc is usually cast to the data WebPointer in C is just a variable that could store the address of the other variable. In C size of a pointer is not fixed as it depends on Word size of the processor. In general a 32-bit computer machine then size of a pointer would be 4 bytes while for a 64-bit computer machine, it would be 8 bytes. Syntax Datatype *variable_name; does u of a play today
