NAME: NAVEEN N USN:1OX12MCA57Program 2a: Write a program in C# to demonstrate Command Line Arguments Processing. Steps to set command line arguments:Step 1: go to project menu -> select project properties optionStep 2: In project property window select debug tab.Step 3: In Debug tab set the argument list in Command line argument text box which we seeing in following window:
