Step by step
Solved in 2 steps
- Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)(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.Please circle True or False for each of the following statements. C++ Variables of type int are initialized to the empty string by default. TRUE FALSE
- In C++ please replace the evaluate function with a single output statement without changing the program behavior. The simplest solution replaces. evaluate(hselect, rselect); with cout << names[0] << ' ' << outcome[?] << " because " << messages[?] << endl; Other solutions are possible. Write the simplicity solution and the similarity of its output to the original program's output. Criteria compile, run, output the program compiles without error, runs without crashing, and, given the same input, produces the same output as the original program. arrays and statements the solution uses 1d arrays effectivelythe solution uses 2d arrays effectivelythe solution replaces the evaluate function with one or more statements containing one or more array referencesbetter solutions replace the evaluate function with more array references and fewer statements.the best solution replaces the evaluate function with one statement that contains five array references.…Hello. I'm working on a triangle and house in C++. I'm a bit confused on how to continue, especially with adding void and arguments. What's Needed: functions in C++. declare function prototypes in C++. use void functions in C++. pass information into functions using arguments. Program Requirement: main should prompt the user for one character and two integer values before drawing a rectangle and triangle by calling the functions appropriately. draw_rectangle is a void function that accepts 3 arguments (the character symbol, integer width, and integer height). It should repeatedly call the draw_bar function to draw the rectangle shape. draw_bar should accept 2 arguments (the character symbol and an integer value width). It will use a loop to draw a horizontal bar of the character. draw_triangle should accept 2 arguments (the symbol and integer height). It should also repeatedly call the draw_bar function to draw the triangle of symbols to the screen as seen in the sample runs.…In C++, State if the following variable names are valid or invalid. If it's invalid, state why. Note: invalid here means creating a syntax error. a) 1wayTicket b) employee_pay c) #zombies d) R66Y e) STOP! f) Final Exam

Then, displays the charges based on the rates shown in Figure 2 below : Age Range Rate ( per hour) (RM)0-20 1.0021-50 3.50Above 50 2.00 In your program, you have to make use of THREE(3) different defined constants for the value of rate per hour and declare the necessary variables.
- Please circle True or False for each of the following statements. C++ The return type void indicates that a function will perform a task but will not return any information upon completion of that task. TRUE FALSEWrite C++ statements that accomplish the following. Declare int variables x and y. Initialize x to 25 and y to 18. Declare and initialize an int variable temp to 10 and a char variable ch to 'A'.
