Exercise 1: Copying Files
Write two programs that
- takes input file name F as
argv[1]
- checks for existence/readability of F
- takes output file name G as
argv[2]
- opens file G for writing (truncate)
- copies the content of F into G
Implement them using:
- character-by-character input/output
- line-by-line input/output
- read/write using large memory buffer
