Question $4$: What is the difference between

print$("$The circle circumference is $"+$str$($c$)+"$ and the area is $"+$str$($a$))$

and

print$("$The circle circumference is $")$

print$($c$)$

print $("$ and the area is $")$

print$($a$)$

$?$

a$)$ Nothing, The output looks identical,

b$)$ The second will not run, because the variables $c$ and a need to be explicitly

converted to strings, using the str$()$ function.

c$)$ The first prints everything on one line, the second prints $4$ separate lines.

d$)$ The first will not run, because only one $+$ sign $($concatenation operator$)$ is

allowed in a line of code.
