Example Program
Obtaining the Sample Program.
This following example program demonstrates the use of exceptions.
#include
#include
static void f() { throw runtime_error("a runtime error"); }
int main ()
{
string s;
// First we'll try to incite then catch an exception from
// the standard library string class.
// We'll try to replace at a position that is non-existent.
//
// By wrapping the body of main in a try-catch block we can be
// assured that we'll catch all exceptions in the exception
// hierarchy. You can simply catch exception as is done below,
// or you can catch each of the exceptions in which you have an
// interest.
try
{
s.replace(100,1,1,'c');
}
catch (const exception& e)
{
cout << "Got an exception: " << e.what() << endl;
}
// Now we'll throw our own exception using the function
// defined above.
try
{
f();
