Document Content and Description Below

What are the value of the variables ‘A’ and ‘B’ at end of the following program? Show your reasoning. Void main (void) { int A; int B; int C; A=5; B=2; C=A*B; A=C*2; B=A/4; C=A - B... ; if ((C – B>A) { A=5; B=C;} else { A=6; B=0; } } 2. (6 pts) What is the value of the variable ‘A’ at end of the following program? Show your reasoning. Void main (void) { int A; int COUNT; A=1; COUNT=0; while (COUNT < 5) { if (COUNT<2) { A=A+4; } else { A=A+COUNT; } COUNT = COUNT +1; 3. (6 pts) Find and indicate all of the errors in the following program. (Hint: one of the errors has to do with an unwanted infinite loop) 4. (3 pts) What is the difference between a digital signal and an analog signal? Hint: Read lecture PowerPoints. Digital Signal Analog Signal 5. (3 pts) There are 5 red LEDs on the electronic board (IRB). Describe what it means when they are on. The answer to this is found in the robot documentation on the web site. Hint: read Robot Guidelines. 1. The 5 LEDs are present in the IRB (Infrared Receiver Board). These 5 LEDs are used for status indication only. They are not serving any purpose for the operation of the board. 2. The LEDs in the faulty unit will ON when there is a fault or error in the board. 3. The LED1, LED2, LED3 shows which IR detector is the active detector. 4. The LED 4 indicates the tuning frequency. 5. The LED 5 indicates the low/high sensitivity setting. [Show More]
