How do I get my function to print from elements.txt $($or any text file$)$ using pointers const char $*$classString;

switch $($classChoice$)\{$

case $1$: classString $=$ "alkali metals"; break;

case $2$: classString $=$ "metalloids"; break;

case $3$: classString $=$ "alkaline earth metals"; break;

case $4$: classString $=$ "reactive nonmetals"; break;

case $5$: classString $=$ "transition metals"; break;

case $6$: classString $=$ "noble gases"; break;

case $7$: classString $=$ "post$-$transition metals"; break;

case $8$: classString $=$ "lanthanides"; break;

case $9$: classString $=$ "actinides"; break;

case $10$: classString $=$ "unknown properties"; break;

default:

printf$("$Invalid class choice.

$")$;

return;

$\}$

FILE $*$file $=$ fopen$("$elements$.$txt$","$r$")$;

if $($file $==$ NULL$)\{$

printf$("$Error opening file.

$")$;

return;

$\}$

element tempElement;

while $($fscanf$($file$,"\%$d $\%14$s $\%2$s $\%24$s $\%$lf$",$ &tempElement.num, tempElement.name, tempElement.symbol, tempElement.elementClass, &tempElement.atomicWeight$)==5)\{$

if $($strcmp$($tempElement$.$elementClass, classString$)==0)\{$

printf$("\%$d $\%$s $\%$s $\%$s $\%$lf

$",$ tempElement.num, tempElement.name, tempElement.symbol,

tempElement.elementClass, tempElement.atomicWeight$)$;

$\}$

$\}$

fclose$($file$)$; This $is$ the code I $am$ working with for reference
