hey

in this code....i have been trying to execute some commands
but this cin.ignore() and getline functions are giving me troubles

if i do not use cin.ignore() then all the if blocks of give_command are skipped and on console i can see

invalid
enter again

after using cin.ignore()
getline is skipping first character of my input and also command is not getting executed.

please help
