POINTER OPERATIONS

POINTER ARITHMETIC OPERATIONS

• ·         Pointers offers arithmetic operations in C-language.
• ·         For normal variables increment, Decrement, postfix and prefix means increment or decrement by value of 1.
• ·         But in pointer variables increment, decrement, postfix and prefix means increment or decrement by address of a variable.
• ·         Arithmetic operations applied on pointers, Not on addresses

/* EXAMPLE PROGRAM FOR POINTER ARITHMETIC OPERATIONS */

main()

{

            int *p,*q,x=20,y=10;

            clrscr();

            p=&x;

            q=&y;

            printf(“Addition=%d”, (*p) + (*q));

            printf(“Substraction=%d”,(*p)-(*q));

            printf(“Multiplication=%d”, (*p) * (*q));

            printf(“Division=%d”,(*p)/(*q));

            getch();

}
