C Programming Exercise: ex1

Write, compile and run two C programs:

1. h2d.c

   This program should prompt for an integer to be read from standard input in hex (using 0 - 9 and a - f 'digits').

   It should then read the value and print the value in hex and in decimal.

   Sample execution:

   $ h2d
   Enter an integer (in hex): a5
   num = 0x000000a5 = 165
   

2. reverse.c

   This program should prompt for an input string of characters.

   It should read the entire line of input into a string variable (char array), removing the trailing newline if necessary.

   Then it should reverse the order of characters in the array and finally, print the reversed string.

   Sample execution:

   
   $ reverse
   Enter a line of input
   Hello, world!
   The input line in reverse order:
   !dlrow ,olleH
   

Submitting your files

From your cdmlinux account:

In the directory containing your h2d.c and reverse.c files, at the prompt ($ or whatever it is) type

 ~glancast/submit373 ex1 h2d.c
    

 ~glancast/submit373 ex1 reverse.c      
    

If you submit this way, you do NOT need to submit these programs on Course Online.

Not using cdmlinux

If you are using your own Linux machine, you can upload your files for assignment ex1 on the Course Online site.
