C++ Exception Handling with Examples (Basic to Advanced)

A brief description of what's inside Section 2 of this course. What topics you should emphasize on and what you will be able to implement at the end of this section.

In this lecture, you will learn understand the concept of Exception Handling, i.e, how it works. You will also know about there words which you should get yourself familiar with, i.e., try, catch and throw.

Try is used for handling the exception. Inside try block we have a throw statement which literally throws something. Finally we have catch block which accepts as a parameter the same data type which we have throw.

In this lecture we will cover another example for Exception Handling. You will again use a try block that throws and integer as a result a catch block that receives an integer (with a formal parameter). Please note - catch Block will always immediately follow try block, no matter what.

A brief description of what's inside Section 3 of this course. What topics you should emphasize on and what you will be able to implement at the end of this section.

In this lecture you will learn how to create a function that generates an Exception. First we will create a try block, and inside it we will call that function that generates an exception. Inside the function definition we will have a throw statement which will throw an exception. A throw block will be there(obviously - everytime you write a try block, make a catch block immediately) which will catch the exception.

An extra lecture for throw keyword. How we can alter or write it in different ways.

A brief description of what's inside Section 4 of this course. What topics you should emphasize on and what you will be able to implement at the end of this section.

In this lecture you will learn the concept of "Multiple catch" statements. It is used so that we can catch different types of data types depending on what data type was thrown from the throw statement. For catching any data type whether it is float, integer, character or double(any) we use (...) inside the catch statement as catch(...) which signifies that any it can catch any type of data thrown.

Another example for "Multiple catch statements" to help you better understand this concept.

A brief description of what's inside Section 5 of this course. What topics you should emphasize on and what you will be able to implement at the end of this section as well as at the end of the course.

Just like we have nested "if statements", we can also create nested try blocks, i.e., another try block inside a try block.

In this lecture you will learn how can we restrict our compiler to throw only certain data types. Now if you throw any other data type other than that you specified your compiler will stop working, since you now have a function that has restricted to throw only certain data types that you specified.

Up till now we were throwing an exception either inside a try block or inside a function that was called from try block. Now we will learn how to put a throw statement inside a catch block by keyword throw; to rethrow the same exception that was being caught by that catch block.
