decompress data from file

[silverarrow]

I have stored some data in a file.txt which is hello ho3w2 are you.
How can I open this file in c compiler and save the data into a new file (file2.txt) as hello hoooww are you(replace no. with char)?

basically i want to read: ho3w2 are you
and store: hoooww are you

can anyone help with some functions to use or sample code?

You have any problems.
