Write a main function that asks the user to choose whether to find the area of a rectangle, the perimeter of a rectangle, the area of a circle or the circumference of a circle. If the user chooses to find the area of a circle use circle_area function, if the user chooses to find the area of a rectangle use rectangle_area function and so on.

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. The following is an extremely useful programming algorithm for rounding a real number to n decimal places: Step 1: Multiply the number by 10n Step 2: Add 0.5 Step 3: Delete the fractional part of the result Step 4: Divide by 10n For example, using this algorithm to round the number 78.374625 to three decimal places yields: Step1:78.374625103=78374.625 Step2:78374.625+0.5=78375.125 Step3:Retainingtheintegerpart=78375Step4:78375dividedby103=78.375 Using this algorithm, write a C++ function that accepts a user-entered value and returns the result rounded to two decimal places. b. Enter, compile, and run the program written for Exercise 11a.
(General math) a. Write a function named rightTriangle() that accepts the lengths of two sides of a right triangle as the arguments a and b. The subroutine should determine and return the hypotenuse, c, of the triangle. (Hint:UsePythagorastheorem,c2=a2+b2.) b. Include the function written for Exercise 4a in a working program. The main() function should call rightTriangle() correctly and display the value the function returns.
(Practice) For the following function headers, determine the number, type, and order (sequence) of values that should be passed to the function when it’s called and the data type of the value the function returns: a. int factorial(int n) b. double volts(int res, double induct, double cap) c. double power(int type, double induct, double cap) d. char flag(char type, float current, float time) e. int total(float amount, float rate) f. float roi(int a, int b, char c, char d, float e, float f) g. void getVal(int item, int iter, char decflag, char delim)
(Physics) Buoyancy is the upward force a liquid exerts on a submerged object, as shown in Figure 6.9. The buoyancy force is given by this formula: B=pgV Bisthebuoyancyforce( lbforN).isthefluiddensity( slug/f t 3 orkg/ m 3 ).gistheaccelerationcausedbygravity( 32.2ft/se c 2 or9.8m/ s 2 ).Vistheobjectsvolume( f t 3 or m 3 ). a. Using this formula, write a function named buoyantForce(double ro, double vol, int units) that accepts a fluid density, the volume of an object placed in the fluid, and the units to be used(1=U.S.Customaryunits,2=metricunits), and returns the buoyancy force exerted on the object. b. Include the function written for Exercise 6a in a working C++ program, and use your program to complete the following chart:

Using python write the following functions: Write the definition of a function that takes one number, that represents a temperature in Fahrenheit and prints the equivalent temperature in degrees Celsius. Write the definition of another function that takes one number, that represents speed in miles/hour and prints the equivalent speed in meters/second. Write the definition of a function named main. It takes no input, hence empty parenthesis, and does the following:- prints Enter 1 to convert Fahrenheit temperature to Celsius- prints on the next line, Enter 2 to convert speed from miles per hour to meters per second.-take the input, call this main input, and if it is 1, get one input then call the function of step 1 and pass it the input.- if the main input is 2, get one more input and call the function of step 2.- if the main input is neither 1 nor 2, print an error message. After you complete the definition of the function main, write a statement to call main.

1) In mathematics, a factorial of a number is calculated by multiplying that number by all of the successive values less than it, stopping at 1. For example, factorial of 4 is written 4! and calculated as: 4! = 4 * 3 * 2 * 1 = 24 2) Write a program consisting of two functions (plus the main function). The first function should read in a number and then return this value back to the main function. This value should then be passed as a parameter (by value) into the second function which calculates and displays the factorial. Note: validate the input value (in the first function) to be greater than 1. 3) Improve your program from question 2, by changing the second function (that calculates the factorial) so that the result is returned to the main function instead of being printed where it is calculated. A new display function should be created and called from the main function that displays the calculated value. 4) Write a program that reads in two numbers and stores them into two…
write a function get_intersecting_station(line_one, line_two) where line_one and line_two are the colors of the lines. This function should return the name of the station where the two lines intersect. Recall from our simplification, there will be only one. If there is no intersecting station, return None use python
Write a Python function def getBonus(salary, bonusPercent) The function you write should be named getBonus, and it should accept an employee’s salary and the bonus they have been granted, and then return the bonus amount.
