$2\mathrm{.}31$ LAB: Warm up: Variables, input, and casting

$(1)$ Prompt the user to input an integer, a double, a character, and a string, storing each into separate variables. Then, output those four values on a single line separated by a space. $(2$ pts$)$

Note: This zyLab outputs a newline after each user$-$input prompt. For convenience in the examples below, the user's input value is shown on the next line, but such values don't actually appear as output when the program runs. Use next$()$ to read String, not nextLine$().$

Enter integer:

$99$

Enter double:

$3\mathrm{.}77$

Enter character:

z

Enter string:

Howdy

$993\mathrm{.}77$ z Howdy

$(2)$ Extend to also output in reverse. $(1$ pt$)$

Enter integer:

$99$

Enter double:

$3\mathrm{.}77$

Enter character:

z

Enter string:

Howdy

$993\mathrm{.}77$ z Howdy

Howdy z $3\mathrm{.}7799$

$(3)$ Extend to cast the double to an integer, and output that integer. $(2$ pts$)$

Enter integer:

$99$

Enter double:

$3\mathrm{.}77$

Enter character:

z

Enter string:

Howdy

$993\mathrm{.}77$ z Howdy

Howdy z $3\mathrm{.}7799$

$3\mathrm{.}77$ cast to an integer is $3$
