C Programming:

My Question: How to use C language to ask filename from user and put file contents in a buffer and update the count of bytes/words? (how to write getFname(..) method in C?)

typedef unsigned short u short; typedef unsigned int u int32; typedef unsigmed long u int64 uint64 getCode ( *buffer, int count) /* count = byte/word count */ egister u int64 total-0: ile (count- return XXXx; int main(...) I - ask filename from user and put file contents in a buffer and update the count of bytes/words. call getCodeOfunction to calculate code using one's complement. getFname (...) code -getcode (buffer,count) use code to validate any user-specified file'/ getFname (...) testvalidity (code, Fname)
