Try-catch

In C++, basic exception handling is done using the try, catch, and throw keywords to manage runtime errors in a controlled manner. This allows the program to handle unexpected conditions gracefully, without crashing, and gives the developer a way to respond to different types of errors effectively.

Key Components:

The catch block handles the exception thrown by the throw statement. It specifies the type of exception it can catch, and if the thrown exception matches, the catch block is executed. Multiple catch blocks can be used to handle different types of exceptions.

try Block:

The try block contains code that may potentially generate an exception. If an exception occurs within this block, the flow of control is transferred to the corresponding catch block.

throw Statement:

The throw statement is used to signal that an error or unexpected condition has occurred. It can be used to throw an exception from within a try block. When a throw statement is executed, the program exits the try block and searches for a matching catch block.

catch Block:

try {
    // try to execute this block of code
}
catch (ExceptionName e) {
    // code to handle exception
}
catch (ExceptionName1 e) {
    // code to handle exception
}
catch (ExceptionName2 e) {
    // code to handle exception
}
