int n;
double fee;
char response1,response2;
char i,o,u,g;
inFile.open("registration fee.txt");
cout<<"please enter your status of residence,type i or o"<<endl;
cin>>response1;
cout<<"please enter your status of study,type u or g"<<endl;
cin>>response2;
cout<<"please enter your number of credits"<<endl;
cin>>n;
i = 0;
u = 0;
if ((response1 == i)&& (response2 == u))
{
if (n < 12)
{
fee = ((280 *n *0.35)+ (43 * n));
cout<<"status of residence : " << response1<<endl;
cout<<"status of study : "<<response2<<endl;
cout<<"number of credits : "<<endl;
cout<<fee<<endl;
if (n >= 12)

cout<<"status of residence : " << response1<<endl;
cout<<"status of study : "<<response2<<endl;
cout<<"number of credits : "<<endl;
}
}
}
g = 0;
if((response1 == i) && (response2 == g))

A few things that stand out are:
-You're reading a file but what are you actually doing with it?
Those letters should be surrounded with apostrophes like so
-Are those nested if statements actually what you want? I don't think so.
I don't know, have a look at the code below....

Can you explain what the file is for though? Or are you going to work on that now?  |
