Pre: 1. Brows to https://repl.it/languages/c 2. Continue as Anonymous (you can also make a new account or login if you have already created an account last week) 3. Download Lab10.c from canvas and copy the code to your online IDE. Task A: Due at the End of the lab (L01:10:45 am, L02:1:45 pm, L03: 4:45pm) 1. Download C_Programming_Reference.pdf 2. Review the Lab10.c code and add proper comments where asked://*** ADD COMMENTS 3. Declare a new function fourBitAdder as: adder_type fourBitAdder(int a, int b, int carryln); 4. Implement the fourBitAdder function with using four oneBitAdder functions. You may use helper variables to pass the values between functions. 5. Use fourBitAdder function in a for loop to increment a number 15 times. That is, starting with a sum of 0, add 1 to it 15 times. 6. Assume each loop iteration takes 1000 ns (int opTime = 1000;). Your program should report the total execution time of the for loop. (add opTime + =1000; at end of for loop). Task B: Due: May 2nd, 2017 Using oneBitAdder function and helper variables, implement a 4-bit adder pipeline. Pre: 1. Brows to https://repl.it/languages/c 2.
