Tenth chapter arrays and pointersProgramming exercises1. Modify the program in Listing 10.7 rain so that it does not use array subscripts, but instead use pointers for calculations (you still need to declare and initialize the array in your program).#include2. Write a program that initializes a double array, and then copies the contents of the array to the other two (3 arrays need to be declared in the main program).The function that makes the first c

Actually feel that the tenth chapter also has no content, is nothing more than to say some of the underlying IO functions, and tell you that these things basically no use, generally still want to use UNIX to the standard IO function ...
