Re: [c-prog] try catch

[Robert Ryan]

I put another brace before the first catch and I still get errors

try {
while (cin) {
        cout << expression() << '\n';
        keep_window_open();
}
}

.cpp: In function `int main()':
.cpp:12: parse error before `&' token
.cpp:12: syntax error before `&' token
.cpp:14: ISO C++ forbids declaration of `keep_window_open' with no type
.cpp:15: parse error before `return'
.cpp:19: ISO C++ forbids declaration of `keep_window_open' with no type
.cpp:20: parse error before `return'

 Your while loop is closed but your try isn't. It should be like
 
 try {
    while {
       ...
     }
 }
 catch ...
