C++ Tutorial => try

Example

The keyword try is followed by a block, or by a constructor initializer list and then a block (see here). The try block is followed by one or more catch blocks. If an exception propagates out of the try block, each of the corresponding catch blocks after the try block has the opportunity to handle the exception, if the types match.

std::vector<int> v(N);     // if an exception is thrown here,
                           // it will not be caught by the following catch block
try {
    std::vector<int> v(N); // if an exception is thrown here,
                           // it will be caught by the following catch block
    // do something with v
} catch (const std::bad_alloc&) {
    // handle bad_alloc exceptions from the try block
}
