Function Try Block for regular function

void function_with_try_block() 
try
{
    // try block body
} 
catch (...) 
{ 
    // catch block body
}

Which is equivalent to

void function_with_try_block() 
{
    try
    {
        // try block body
    } 
    catch (...) 
    { 
        // catch block body
    }
}

Note that for constructors and destructors, the behavior is different as the catch block re-throws an exception anyway (the caught one if there is no other throw in the catch block body).

The function main is allowed to have a function try block like any other function, but main’s function try block will not catch exceptions that occur during the construction of a non-local static variable or the destruction of any static variable. Instead, std::terminate is called.
