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 demos of 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' Please input your integer decimal number: 0000000000000000000000000001100 12 Case 2: Input a negative number (the binary number should be in 2's complement format): **Please select the following options 1.

To Exit, Type 'e' 1 Please input your integer decimal number: -20 11111111111111101100 Please follow the following requirements for this lab: 1. Must have your comments on each line of the source code to explain your code. 2. At the start of the source code, you must type in your name and student ID as the comments. 3. Must include the screenshots of at least two integer numbers (one signed and one unsigned
