1. Using C#, implement a console application of the source code of a lexical analyzer (front.c) on page 166 in the textbook. Your console application should receive an input (for example sum + 56/total) and give the similar output like on page 171. All the things you need to refer to are below. The code below is in C. thanks.

output on page 171 below:
