1. Mark the following statements as true or false. a. The calculating device called the Pascaline could calculate sums up to eight figures long. (1) b. All programs must be loaded into the CPU before they can be executed and all data must be loaded into main memory before it can be manipulated. (2) c. Main memory is an ordered sequence of cells and each cell has a random location in main memory. (2) d. The program that loads first when you turn on your computer is called the operating system. (2) e. Analog signals represent information with a sequence of 0s and 1s. (3) f. The machine language is a sequence of 0s and 1s. (3) g. A Binary code is a sequence of 0s and 1s. (3) h. A sequence of eight bits is called a byte. (3) i. One GB is MB. (3) j. In ASCII, A is the 65th character. (3) k. The number system used by a computer is base 2. (3) l. An assembler translates the assembly language instructions into machine language. (4) m. A compiler translates the source program into an object program. n. In a program, statements that begin with the symbol are called preprocessor directives (7) o. An object program is the machine language version of a high-level language program. (9) p. All logical errors, such as division by 0, are reported by the compiler. (9) q. In object-oriented design (OOD), a program is a collection of interacting objects. (10) r. An object consists of data and operations on that data. (10) s. ISO stands for International Organization for Standardization. (11)

(Practice) a. Write a declaration statement to declare that the variable count will be used to store an integer. b. Write a declaration statement to declare that the variable volt will be used to store a floating-point number. c. Write a declaration statement to declare that the variable power will be used to store a double-precision number. d. Write a declaration statement to declare that the variable keychar will be used to store a character.

(For thought) a. What’s an advantage of namespaces? b. What’s a possible disadvantage of namespaces?

(Numerical) a. Write a C++ program that accepts an integer argument and determines whether the passed integer is even or odd. (Hint: Use the % operator.) b. Enter, compile, and run the program written for Exercise 8a.

(Program) Write a C++ program that displays the results of the expressions 3.05.0,7.18.32.2,and3.2/(6.15) . Calculate the value of these expressions manually to verify that the displayed values are correct.

(General math) a. Write, compile, and run a C++ program to compute and display the value of the second-order polynomial ax2+bx+c for any user-entered values of the coefficients a, b, c, and the variable x. Have your program display a message to inform users what the program does, and then display suitable prompts to alert users to enter the data. (Hint: Use a prompt such as Enter the coefficient of the x-squared term:.) b. Check the result of your program written for Exercise 7a by using the following test data: Testdataset1:a=0,b=0,c=22,x=56Testdataset2:a=0,b=22,c=0,x=2Testdataset3:a=22,b=0,c=0,x=2Testdataset4:a=2,b=4,c=5,x=2 After finishing your verification, use your program to complete the following chart

(Physics) Coulomb’s Law states that the force, F, acting between two electrically charged spheres is given by this formula: F=kq1q2r2 q1isthechargeonthefirstsphere.q2isthechargeonthesecondsphere.risthedistancebetweenthecentersofthetwospheres.kisaproportionalityconstant. Write an assignment statement to calculate the force, F.

In a C++ program, preprocessor directives begin with which symbol? (8)

(General math) The value of p can be approximated by this series: 4(113+1517+....) Using this formula, write a program that calculates and displays the value of , using 2, 3, and 4 terms of the series.
