(True/False): A sector consists of multiple tracks.

(Desk check) Determine the value in total after each of the following loops is executed: a.total=0;for( i=1;i=10;i=i+1)total=total+1;b.total=1;for( count=1;count=10;count=count+1)total=total2;c.total=0;for( i=10;i=15;i=i+1)total=total+i;d.total=50;for( i=1;i=10;i=i+1)total=totali;e.total=1;for( icnt=1;icnt=8;++icnt)total=totalicnt;f.total=1.0;for( j=1;j=5;++j)total=total/2.0;

(For review) List the three repetition statements provided in C++.

(Practice) Show how the name KINGSLEY is stored in a computer that uses the ASCII code by drawing a diagram similar to Figure 2.7, shown previously.

(For review) a. What’s the difference between a pretest and posttest loop? b. If the condition being tested in a pretest loop is false, how many times are statements in the loop executed? c. If the condition being tested in a posttest loop is false, how many times are statements in the loop executed?

If 2 bits of a byte are in error when the byte is read from ECC memory, can ECC detect the error? Can it fix the error?

(Practice and modify) a. Enter and run Program 8.6. b. Modify Program 8.6 by replacing cout with cerr, and verify that the output for the standard error stream is the screen. c. Modify Program 8.6 by replacing cout with clog, and verify that the output for the standard log stream is the screen.

(Electrical eng.) a. Write, compile, and run a C++ program that calculates and displays the value of the current flowing through an RC circuit (see Figure 3.19). The circuit consists of a battery connected in a series to a switch, a resistor, and a capacitor. When the switch is closed, the current, i, flowing through the circuit is given by this formula: i=(EIR)et/RC Eisthevoltageofthebatteryinvolts.Risthevalueoftheresistorinohms.Cisthevalueofthecapacitorinfarads.tisthetimeinsecondsaftertheswitchisclosed.eisEulersnumber,whichis2.71828( roundedtofivedecimalplaces). Using this formula, write, compile, and run a C++ program to determine the voltage across the capacitor shown in Figure 3.19 when t is 0.31 seconds. (Note: The value of RC is referred to as the system’s time constant.) The program should prompt the user to enter appropriate values and use input statements to accept the data. In constructing the prompts, use statements such as “Enter the voltage of the battery.” Verify your program’s operation by calculating by hand the current for the following test data: Testdataset1:Voltage=20volts,R=10ohms,RC=0.044,t=0.023secondsTestdataset2:Voltage=35volts,R=10ohms,RC=0.16,t=0.067seconds b. Check the value computed by your program by hand. After verifying that your program is working correctly, use it to complete the following chart:

___________ occurs when the result of an arithmetic operation exceeds the number of bits available to store it.

(Practice) Write a C++ program to create the pollen.in file shown in Figure 8.3.
