Operations on Pointers in C

The only operations that can be carried out on pointers in C are summarized below: A pointer variable in C can be assigned the address of an ordinary variable (e.g., pv = &v) A pointer variable can be assigned the value of another pointer variable (e.g., pv = px) provided both the pointers point to objects of the same data type A pointer variable in C can be assigned a null (zero) value (e.g., pv = NULL, where NULL is a symbolic constant that represents the value 0) An integer quantity can be added to or subtracted from a pointer...

Passing pointers to functions in C

Pointers in C are often passed to a function as arguments. This allows data items within the calling portion of the program to be accessed by the function, altered within the function, and then returned to the calling portion of the program in altered form. We call this use of pointers in functions as passing arguments by reference (or by address or by location), in contrast to passing arguments by value. When an argument is passed by value, the data item is copied to the function. Thus, any alteration made to the data item within the function is not carried...
