In this part, he provides an in-depth, step-by-step explanation of classes, interfaces, and object-oriented programming with C#. An exception is defined as an event that occurs during the execution of a program that is unexpected by the program code. The actions to be performed in case of occurrence of an exception is not known to the program. In such a case, we create an exception object and call the exception handler code.

The foreach loop is used to iterate over the elements of the collection. For loop has similar functionality as while loop but with different syntax. For loops are preferred when the number of times loop statements are to be executed https://remotemode.net/ is known beforehand. The loop variable initialization, condition to be tested, and increment/decrement of the loop variable is done in one line in for loop thereby providing a shorter, easy to debug structure of looping.
