pointer A is a variable that stores the address of another variable =>Provides another way to re fu to a variable, through its address ratger tgab its symbolic name -Declaration int *p; Setting Pointers: int a, *p, *g; p = &a; // & means 'address of int', p is the address of a g = p; // g has the same address of p Access through Pointers: int a, x, y, *p; p = &a; x = *p + y; // pointer dereference *p = x + y; Memory ---------| | | | ---------0021303 | a ---------| | | | ---------0021323 | p ---------| | | | ---------- | // a is a variable; we make the address p to indicate the location of a; | // p is the location of a; but p also has a location 'int **p;' Printing Pointers: printf("%p", // p); print the thing stored in p III .pointer arithmetic Adding a value to a pointer changes the pointer in increments of the sign of the element being pointed to: (e.g.) Int a, *p; Double b, *g; P = &a; P = P + 5; If &a = 0x100, then p = 0x100 + (4*5) = 0x114 //4 is for int, 4 bites G = &b; G = g+3; If &b = 0x200, then p = 0x200 + (8 *3) = 0x218 //8 is for double, 8 bites P++; => 0x114 + 4 = 0x118 G++; => 0x218 +8 = 0x220 *(a+i) = &a[i] IV. Pointers and Function Arguments Int main() { Int x = 5; Foo(x); } Void foo (int z) { Int y; Y = z + 10; Z = 7; } Int main() { Int x = 5; Foo(&x); } Void foo (int *z) //int * is pointer declaration { Int y; Y =* z + 10; Z = 7; }
