Using Files
Using fopen():
- In different applications, we may need to open a file in different ways:
“r” open for reading
“r+” open for reading and writing
“w” create or truncate file, then open for writing
“w+” create or truncate file, then open for reading and writing
“a” create if necessary, then open for appending (at the end of the file)
“a+” create if necessary, then open for reading and appending - Truncate means to empty a file, but to still keep the file
i.e. clear a file
