I have a UTF-8 string in from which i want to find out which are non-ASCII characters.

lets say i have char arr[] = "x√ab c"; , and it has 1 non-ASCII character (√')

one way it to find the ascii characters from given UTF-8 string , excluding those i'll get the non-ASCII characters.

Given the following information from https://en.wikipedia.org/wiki/UTF-8#Description:
info 1:

One-byte codes are used only for the ASCII values 0 through 127. In this case the UTF-8 code has the same value as the ASCII code. The high-order bit of these codes is always 0

info :2

another way is to find the UTF-8 code for a character. All ASCII character are range from U+0000 to U+007F

Using the any of the above info , how can i find non-ASCII character ? (or if there is any other way to find )

FYI:using gcc compiler

Thanks

hi ranchers,

Need suggestion for developing the Gui interface of Conway Game of Life. I think Swing does not have components to display a grid of cells.

Please suggest a library or api to create a gui.

guidance regrading a project

hi ranchers,
I have given a project assignment of a web crawler with specific reqiurements as following:

when user searches for a product name like samsung , iphone, etc. it can be any product.

1. the web crawler has to find first 10 links that Google searches for that product.
2. For each of those link It had to find images , link, contact detail ,article , facebook page,twitter page.
3. display all these info in a html page

Now i have specific questions:
how can i find first 10 pages of Google for particular input (in my case a product) ?
Is there third-party library which can be useful ?

Any guidance in this regard be appreciated.
