Pointers C Slides Pdf Pointer Computer Programming Variable Definition: a pointer is a variable that holds memory address of another variable, where, the actual data is stored. by using pointers, it is an efficient way of accessing and manipulating data. memory, registers and cache are scarce resource in computer system. The document discusses the concept of pointers in programming, explaining that a pointer is a variable that holds the memory address of another object. it covers types of pointers, pointer arithmetic, comparisons, and benefits such as improved efficiency and dynamic memory allocation.

. 7.8 pointer expressions and pointer arithmetic • arithmetic operations can be performed on pointers • increment decrement pointer ( or ) • add an integer to a pointer ( or = , or =) • pointers may be subtracted from each other • operations meaningless unless performed on an array.

The c programming power point, ppt, pdf, swf and mp4 video lecture notes and training material for c short course training with code examples. The document discusses pointers and strings in c programming. it covers pointer basics like declaring, initializing, and dereferencing pointers. it also discusses parameter passing mechanisms like call by value and call by reference. operations on pointers like assignment, arithmetic, and comparison are explained. • the following is a general form for declaring a pointer variable, type of stored data * pointer variable name; • for example, char* chname; int * ntypeofcar; float *fvalue; • type of stored data is any valid pointer base type such as char, int, float or other valid c derived types such as array and< strong> struct. Summary • a pointer stores the address (memory location) of another entity • address of operator (&) gets the address of an entity • de reference operator (*) makes a reference to the referee of a pointer • pointer and array • pointer arithmetic.
