{
	"action" : "login",
	"username" : "alfredgamer",
	"password" : "defnot12345",
}

split string @ '"action" : "'
	assuming c++ uses arrays of some sort
	
	split aboveresult[1] @ '",\n	"username" : "'
	action = aboveresult[0]
	split aboveresult[1] @ '",\n	"password" : "'
	username = aboveresult[0]
	split aboveresult[1] @ '",'
	password = aboveresult[0]
	
	so you should end up with 
	action = "login"
	username = "alfredgamer"
	password = "defnot12345"
