Formative Assessment Input $1$

What happens when code is run with input$()$ vs input$($x$)?$

input$()$ will wait for the user to type something, while input$($x$)$ will print the letter x prior to collecting the input.

input$()$ and input$($x$)$ do exactly the same thing; using an argument is optional.

input$()$ will not store anything that was input, while input$($x$)$ will store what was typed into the variable x$.$

input$()$ will collect input without any prompt to the user while input$($x$)$ will print out whatever value is stored in the variable x prior to collecting the input.
