Change this program: void schedule$\_$save$()\{$

FILE $*$fileptr;

fileptr $=$ fopen$("$course$\_$collection.txt$","$r$")$;

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

printf$("$You need to create the file to save first.

$")$;

$\}$

else $\{$

char line$[512]$;

printf$("$Subject$,$ number, credit & teacher

$")$;

while $($fgets$($line$,$ sizeof$($line$),$ fileptr$))\{$

char $*$index $=$ strtok$($line$,"")$;

char $*$subject $=$ index;

index $=$ strtok$($NULL$,"")$;

int number $=$ atoi$($index$)$;

index $=$ strtok$($NULL$,"")$;

int creditHours $=$ atoi$($index$)$;

index $=$ strtok$($NULL$,"")$;

char $*$teacher $=$ index;

printf$("\%$s$\backslash$t$\%$d$\backslash$t$\%$d$\backslash$t$\%$s

$",$ subject, number, creditHours, teacher$)$; $//$print file

$\}$

$\}$

$\}$

Make it so it loads the file and is named schedule$\_$load
