Pointer variables may be subtracted from one another. Pointer variables can be used in comparisons, but usually only in a comparison to null. Winter quarter Arithmetic Operations on pointers When an integer is added to or subtracted from a pointer, the new pointer value is changed by the integer times the number of bytes in the data variable the pointer is pointing. For example, if the pointer valptr contains the address of a double precision variable and that address is, then the statement: valptr valptr 2; would change valptr to winter quarter Using the c language Special keyword sizeof This keyword can be used to determine the.

Pointers winter quarter pointers and Functions pointers can be used to pass addresses of variables to called functions, thus allowing the called function to alter the values stored there. We looked earlier at a swap function that did not change the values stored in the main program because only the values were passed to the function swap. This is known as "call by value". Winter quarter pointers and Functions If instead of passing the values of the variables to the called function, we pass their good addresses, so that the called function can change the values stored in the calling routine. This is known as "call by reference" since we are referencing the variables. The following shows the swap function modified from a "call by value" to a "call by reference". Note that the values are now actually swapped when the control is returned to main function.
