In Linux using c + + write a choice difficulty typing game
The ideal output should be morally for such

Actual output became the ghost sample, please help!

The code is as follows:

 # define TTY_PATH "/dev/tty 
"# define STTY_US "stty raw echo - F" 
# define STTY_DEF "stty - the raw echo - F"

return 0; 
} 

 char putc ()//generate random letters
