Point at the program. Right-click it and choose Closefrom the menu.
The cursor. AKA mouse, pointer, arrow, annoying white thing that sometimes doesn't move fast enough.
That depends on which pole of the magnet it is moved close to. If it is brought close to the "South" pole of the magnet, the "North" pointer of the compass will be attracted to the magnet. If it is brought close to the "North" pole of the magnet, the "North" pointer of the compass will be repelled and will point AWAY from the magnet, while the "South" end of the compass pointer will point to the magnet.
A pointer stores a relative memory link to a place where a variable's data is stored. This mechanism allows the OS to allocate memory to programs as necessary. It is considered "dangerous" to use pointers, as a single pointer can cause a program to crash, although these are exclusively programmer's error.
An icon is an image representation of a program, a shortcut, or a script. For instance on your desktop those pictures that are on programs, and shortcuts such as My computer are icons. So to wrap it up an icon is an image representation of a program like firefox being a fox on a globe and internet explorer being an E with a yellow circle or even safari being a compass. A mouse pointer is exactly the same as a mouse curser. When you move you mouse don't you see that little arrow the you move on the screen. That's what is referred as a mouse pointer. Where you click programs and links that arrow or somethings a hand on a link is a mouse pointer!
1. pointer to a constant means you can not change what the pointer points to 2. constant pointer means you can not change the pointer.
Example: int x; -- integer int *px= &x; -- pointer to integer int **ppx= &px; -- pointer to pointer to integer int ***pppx= &ppx; -- pointer to pointer to pointer to integer
A pointer only holds an address information (location) in the memory. if a pointer holds points another pointer then it is a pointer to an other pointer. Pointer holds an address in the memory so in that address there is an other location information that shows another location.
pointer is the variable that holds the address of another variable
Double pointer is a pointer to a pointer. So you can work with the double pointer as you work with a single one.Or you might mean 'pointer to double', eg:void clear_double (double *dp){*dp = 0;}
Double (**) is used to denote the double pointer. As we know the pointer stores the address of variable, Double pointer stores the address of any pointer variable. Declaration : int **ptr2Ptr;
Pointer to Pointer is a double pointer, denoted by (**). Pointer stores the address of the variable and pointer to pointer stores the address of a pointer variable and syntax can be given as int **ptr2ptr;
Void pointer can hold the address of any kind of pointer. But we can't operate on void pointer
