When constructing an instance of a structure, what kind of effects does using the new operator have?

(Conversion) Write a C++ program to convert kilometers/hr to miles/hr. The program should produce a table of 10 conversions, starting at 60 km/hr and incremented by 5 km/hr. The display should have appropriate headings and list each km/hr and its equivalent miles/hr value. Use the relationship that 1 kilometer=0.6241miles.

Mark the following statements as true or false. All members of a struct must be of different types. (1) A struct is a definition, not a declaration. (1) A struct variable must be declared after the struct definition. (1) A struct member is accessed by using the operator :. (2) The only allowable operations on a struct are assignment and member selection. (2) Because a struct has a finite number of components, relational operations are allowed on a struct. (2) Some aggregate input/output operations are allowed on a struct variable. (2) A struct variable can be passed as a parameter either by value or by reference. (4) A function cannot return a value of the type struct. (4) An array can be a member of a struct. (6, 7) A member of a struct can be another struct. (8)

(Civil eng.) Write an assignment statement to calculate the linear expansion in a steel beam as a function of temperature increase. The formula for linear expansion, l, is as follows: l=l0(1+(TfT0)) l0isthelengthofthebeamattemperatureT0.isthecoefficientoflinearexpansion.Tfisthefinaltemperatureofthebeam.

(Civil eng.) Write a C++ program to calculate and display the maximum bending moment, M, of a beam that’s supported on both ends (see Figure 3.8). The formula is M=XW(LX)/L, where X is the distance from the end of the beam that a weight, W, is placed, and L is the beam’s length. You program should produce this display: The maximum bending moment is xxxx.xxxx The xxxx.xxxx denotes placing the calculated value in a field wide enough for four places to the right and left of the decimal point. For your program, assign the values1.2,1.3,and11.2toX,W,andL.

(Data processing) a. Declare a single structure data type suitable for a car structure of the type in the following chart: b. Using the data type declared for Exercise 5a, write a C++ program that interactively accepts the chart’s data in an array of five structures. After the data has been entered, the program should create a report listing each car number and the car’s miles per gallon. At the end of the report, include the average miles per gallon for the entire fleet of cars.

(Civil eng.) Write an assignment statement to determine the maximum bending moment, M, of a beam, given this formula: M=XW(LX)L X is the distance from the end of the beam that a weight, W, is placed. L is the length of the beam.

Why do you need to include function prototypes in a program that contains user-defined functions? (5)

(Physics) Write an assignment statement to calculate the elapsed time, in minutes, it takes to make a trip. The formula for computing elapsed time is elapsed time = total distance / average speed. Assume the distance is in miles and the average speed is in miles per hour (mph).

(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.
