I need help

Could someone tell me why my program isnt compiling correctly. I get the ___.exe has encountered a problem and needs to close. We are sorry for the inconvenience. *ERROR*. Here is my code someone please help me.

#include <iostream.h>
#include <fstream.h>








main ()
{

int total=0, c, frogbats[100], truck[100], i, first, second, last, remain;




ifstream get_data ("c:/temp/orders.txt");


for (c=0; c<=6; c++)
{
get_data>>frogbats[c];
cout<<frogbats[c]<<endl;
if (total + frogbats[c]<40)
{
truck[i]=total + frogbats[c];
}




else;

if (frogbats[c]>40)
{
if (frogbats[c]<80)
{
i++;
first= frogbats[c]/2;
second= frogbats[c]/2;
remain= frogbats[c]%2;
last= remain + second;
i++;
}
else (frogbats[c]>80);
{
i++;
first= frogbats[c]/3;
second= frogbats[c]/3;
last= frogbats[c]/3;
remain= frogbats[c]%3;
}
if (remain>1)
{
second++;
last++;
i++;
}



else;
{
last++;
i++;
}
}
}
cout<<total;
return (0);
}

this program is supposed display the number of frogbats in each truck with a limit of forty

Should it have a void or a int?
