BUG BUSTERS: The following is a one$-$shot program, but it won$$t compile. Can you explain why?

scanf$(\%$d$,$ &x$)$;

if$($x $<0)$

printf$($The value entered must be positive!$)$;

printf$($Re$-$run the program and try again!$)$;

else

x$++$;

printf$($Good$,$ the value of x $=\%$d$,$ x $)$;

choose the answer betwen the following :

Improper usage of curly braces $\{\}$ for code blocks.

Missing #include directive.

Missing a semicolon $($;$)$ after scanf$("\%$d$",$ &x$).$

Incorrect format specifier in the printf statements.

Typo in variable names $($X instead of x$).$
