Part 1: Programming (80%) Refer to lab2.c file posted on blackboard, finish functions to print out a given unsigned/signed number into its binary number. The following screenshots are as demos what you should have on your output screen. Pay special attention to "//finish this part...." comments. Case 1: Input a positive number: *******Please select the following options** 1. Convert Integer Number to Binary. (Lab 2) 2. Binary number to signed decimal number conversion.(lab 3) 3. Binary number to Floating number conversion (Lab 3) e. To Exit, Type 'e' 1 Please input your integer decimal number: 12 00000000 00000000001100 Case 2: Input a negative number: **********Please select the following options*** 1.
