Exercise
Write a command-line interface (CLI) program that displays all command-line arguments, seperated by spaces and followed by a newline.
Call to show_args | Output | Exit status |
|---|---|---|
./show_args | show_args (with newline) | 0 |
./show_args hello | show_args hello (with newline) | 0 |
./show_args hello world | show_args hello world (with newline) | 0 |

for - argv must be converted to a std::vector< std::string >
- Use std::copy to display the command-line arguments with std::cout
