Correct Exceptions in C++
- by Dr.Ackula
I am just learning how to handle errors in my C++ code. I wrote this example that looks for a text file called some file, and if its not found will throw an exception.
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
int array[90];
try
{
ifstream file;
file.open("somefile.txt");
if(!file.good())
throw 56;
}
catch(int e)
{
cout<<"Error number "<<e<<endl;
}
return 0;
}
Now I have two questions. First I would like to know if I am using Exceptions correctly. Second, (assuming the first is true) what is the benefit to using them vs an If else statement?
