Printing a substring based on char start and stop number

Roger · 10-18-2009, 12:31 PM

Say I have a string (an array of characters) that is 1000 characters long. I want to print a substring made up of the characters 50 to 100. How do I do that?

-I have looked at the string library and don't recognize a solution.
-Should I create a new smaller array somehow --- perhaps a loop?

yep, I'm a newb.

You need to look at the string library again, with the caveat that the words they use may not exactly match the words you are using. For instance, there's strncpy.

If you just want to print it, simply start at index 49 and print up to index 99. If you want to make a copy use a similar approach, but instead of printing, copy the data to a buffer somewhere (don't forget to null terminate the string, though).
