During execution of the program, the system always associates the name xyz with the address 1380. the value 50 can be accessed by using either the name xyz or the address 1380.
Pointer Basics An Introduction To Pointers Declaring Pointers All uninitialized pointers will have some unknown values that will be interpreted as memory addresses. they may not be valid addresses or they may point to some values that are wrong. once a pointer variable has been declared we can use the assignment operator to initialize the variable. Pointer variables pointer variables are yet another way using a memory address to work with a piece of data. pointers are more "low level" than arrays and reference variables. this means you are responsible for finding the address you want to store in the pointer and correctly using it. Pointer arithmetic can be used to adjust where a pointer points; for example, if pc points to the rst element of an array, after executing pc =3; then pc points to the fourth element. A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. like any variable or constant, you must declare a pointer before you can use it to store any variable address.

Arrays and pointers example: a program to compute the class average of the midterm. scalar form: de1); scanf(“%d”,&grade2); sum = grade1; sum = grade2;. The difference between constant pointer and the pointer variable is that the constant pointer cannot be incremented or changed while the pointer to an array which carries the address of the first element of the array may be incremented. When we try to “delete” or free the memory pointed to by names[i], it will now try to return memory it didn’t even allocate (i.e. temp buf) and cause the program to crash!. What is an array? the shocking truth: you’ve been using pointers all along! every array is pointer to a block of memory.
