I still dont know how to embed it...
Is it correct as follows?There is still error in VC++.
Is there any C program run the following code without errors?





#include <stdio.h>
#include...

The code can't be run in VC++, it showed a error message:

error C2065: 'randomize' : undeclared identifier

why?

And can I use "time" to generate random numbers?
What's the code?

How can I detect a null string?
--if a user type nothing but simply a "Enter" key then a message is shown

Generate a positive random integer. Add this integer to the ASCII equivalent of each...

I have to creat a program:

1.enter a line of text and convert to ASCII
2.encode the text by adding a random nunber to the ASCII char.


#include <stdio.h>
#include <string.h>
#include...
