Files problem

Can anyone help me with this problem?:
Write a programm that converts a text file cu externs decimal reprezentations into a binary file with they're interns reprezentations.The file's specifiers are given as arguments in the command line.(sorry about my bad english):smiley:

Is this homework? If so please post it in the homework section.

Bad English is one thing, but it is also a bit difficult to understand what you wrote. Are you talking about converting a text file with external decimal representations into a binary file with internal decimal representations? What do you mean with "the file's specifiers " ?

-> Please show a representative sample of input, desired output, attempts at a solution and specify what OS and versions are being used...

Thank you.I will look for the homework section.
