In Example 1-1 (Chapter 1), we designed an algorithm to find the perimeter and area of a rectangle. Given the length and width of a rectangle, the C++ program, in Example 2-1, computes and displays the perimeter and area. The following are identifiers in C++: First Conversion payRate counter1 Table 2-1 show some illegal identifiers […]

You are given a list of students’ names and their test scores. Design an algorithm that does the following: a. Calculates the average test scores. b. Determines and prints the names of all the students whose test scores are below the average test score. c. Determines the highest test score. d. Prints the names of

Design an algorithm to find the real roots of a quadratic equation of the form ax2+ bx +c =0 , where a, b, and c are real numbers, and a is nonzero.   A student spends a majority of his weekend playing and watching sports, thereby tiring him out and leading him to oversleep and

Suppose that num1, num2, and num3 are int variables and the following statements are executed in sequence. 1. num1 = 18; 2. num1 = num1 + 27; 3. num2 = num1; 4. num3 = num2 / 5; 5. num3 = num3 / 4; The following table shows the values of the variables after the execution

Consider the following C++ floating-point expressions: 12.8 * 17.5 – 34.50 x * 10.5 + y – 16.2 Here, x and y are variables of type double. The following C++ program evaluates the preceding expressions:

6.     Write an object-oriented program in C++ to generate the following series of numbers using constructor, destructor and inline member functions.

The C11 program in Example 2-18 illustrates how to read strings and numeric data. The following statements are examples of variable declarations: int a, b, c; double x, y The following statements are examples of executable statements: a = 4; //assignment statement cin >> b; //input statement cout < a=””>< “=”” “=””>< b=””>< endl;=”” output=””>

Part 2. Interest calculations.Ask the user to enter a principal amount, in dollars and cents. Then ask the user for the annual interest rate. A rate of 5.25% per year would be entered as 5.25.(a) Calculate the interest earned for one year, compounded annually. Display the inputs, the interest earned, and the total balance at

If int x = 10;, int y = 7;, double z = 4.5;, and double  w = 2.5;, evaluate each of the following statements, if possible. If it is not possible, state the reason. a. (x + y) % x  b. x % y + w c. (z – y) / w d. (y +

Before starting this class, many of you probably thought that Excel was simply a spreadsheet program used by accountants. In reality, Excel has functions that we can use in our daily lives. For this assignment, draft a two-page essay in which you describe how Excel can be used in each of the following areas of
