The program is to be terminated when we get a ‘x’ or a ‘X’ .When we give a ’ ; ’ (semicolon) character to it , it prints “Invalid Character , try again”. After that we give it a ‘X’ and the loop stops as per our condition and our program ends. This is what is supposed to happen with the sample testcase.
