angular 7 does not ask if to use routing when i create a new project
ng new {Project-name}
command by default creates project without routing.
You need to set routing flag as true while creating project as below(by default this routing flag will be false),
ng new {Project-name} --routing=true
Go through angular documentation for more details
ng new --help
run this command this will open up the things you can do while creating project.
Lets say I wanna create Angular project with routing and .scss styles then I would do it by the following command.
ng new project-name --routing=true --style=scss
