This is a C language program;

$1-$ I need to add a header named $($Volume$).$ And display the volume column, and using this formula calculation, $($Radius$*200)$ to display the volume data

$2-$ The output columns should be aligned and organized.

Below is my $($orbit$.$csv file$)$

Name, Radius, $($Volume$),$Polar$\_$R

earth, $2\mathrm{.}4,1140,$

mars, $6\mathrm{.}3,2334,$

saturn,$3\mathrm{.}3,5719,$

Neptun,$2\mathrm{.}5,4753,$

Below is my Code:

#include

#include

#include

int main$()$

$\{$

FILE $*$fp $=$ fopen$("$orbit$.$csv$","$r$")$;

int ch $=$ getc$($fp$)$;

printf$("\%-30$s $\%-11$s $\%8$s $\%25$s

$",$ "Name", "Radius", "Volume", "Polar$\_$R$")$;

while$($ch $!=$EOF$)\{$

putchar$($ch$)$;

ch $=$ getc$($fp$)$;

$\}$

if $($feof$($fp$))$

printf$("$

End of file."$)$;

else

printf$("$

Press $1$ to exit"$)$;

getchar$()$;

return $0$;

$\}$
