Question:- In this Problem, you have to open a program ( Code ) Itself in console so likely we open any file in console so in place of any file write to program name with extension your file will be open or you can say you the same program will be open 

Explanation:- So basically we have to take an input from a filename as a source of program name with the extension .c/cpp/.java and many other and hit the enter after hitting enter program itself will be print on the console screen or we can say that .c/cpp/.java file contains with these extensions will be printed on screen. In other words, we can say that program itself will be open.
