Question

I am reading data from text file and there is double value which i need to read from the file. Now the problem is that if the double value is invalid for example “!@#$%^&*” then i want my program to give exception so i can handle it. This is my code

void Employee::read(istream &is) {
    try{

        is.get(name, 30);
        is >> salary;
        char c;

        while(is.peek()=='\n')
            is.get( c ); 

    }
    catch(exception e){
    }
}

Answer 1

I finally made it work by setting exception bit on for istream

is.exceptions(ios::failbit | ios::badbit);  //setting ifstream to throw exception on bad data
