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)
1. Write a program in python that contains a main function and a custom, void function named show_larger that takes two random integers as parameters. This function should display which integer is larger and by how much. The difference must be expressed as a positive number if the random integers differ. If the random integers are the same, show_larger should handle that, too. See example outputs. In the main function, generate two random integers both in the range from 1 to 5 inclusive, and call show_larger with the integers as arguments.EXAMPLE OUTPUT 13 is larger than 1 by 2EXAMPLE OUTPUT 2The integers are equal, both are 3
1 - Nuclear Power Plant (python) The nuclear powerplant at Threeyedfish will automatically run a program to print a warning message when the reactor core becomes unstable. The warning message reads: NUCLEAR CORE UNSTABLE!!! Quarantine is in effect. Surrounding hamlets will be evacuated. Anti-radiationsuits and iodine pills are mandatory. Since the message contains crucial information, it should be printed three times. To do this, write a function that prints this message. This function has to be used three times.
task1: write a void function divisor that receives an integer number and display its divisor on screen including 1 and itself. write the main function to test your function. task2: You are required to create a conversion program. First ask the user his choice and then convert. • Conversion from Pound to Kg. (1 Pound = 0.453 Kg) • Conversion from Feet to centimeter (1 Foot = 30.48 cm) • Convert Hours & minutes in Days
int main{void main} { int myArray[100],numint,result; printf("How many numbers to be entered?"); scanf("%d"&numint); getNumbers(myArray,numint); printNumbers(myArray,numint); result=sumNumbers{myArray,numint}; printf("Sum of numbers entered=%d",result); return 0; } Based on this program, write down the function prototype for function getNumber().
Write a function that gets the area of a rectangle. The function must receive two parameters (decimal numbers) that represent the base and height of the rectangle and must return the calculated area (decimal number). Write a second function that obtains the volume of a rectangular prism with a rectangular base. The volume of such a prism is equal to the area of the base times the height of the figure. It uses calls to the previous function for this calculation. Volume=base*height*depth Call this last function in the main with user data. Execution example Give me the base: 21.3 Give me the height: 10 Give me the depth: 2.0 The volume of the prism is: 426.0
Please help me explain the following void function c++ code, which I did not understand. Especially for the first void function and int main(), I do not understand why the first void function enter the number and the int main function print out the final answer. #include <iostream>using namespace std; void getNumber(int *input); void doubleValue(int *val); int main(){ int number; getNumber(&number); doubleValue(&number); cout<<"That value doubled is"<<number<<endl; return 0;}void getNumber(int *input){ cout<<"Enter an integer number:"; cin>>*input; }void doubleValue(int *val){ *val *=2;}
Write a code in the main function that would call Function 1 and Function 3 of the Lab class. You can use values of your choice for function arguments (if required). Please write the output of these function calls. class Lab { int time; public: Lab(){ //Function 1 time = 120; cout << "Duration of lab is " << time << “minutes” << endl; } void Demonstration(){ //Function 2 cout << "Lab Demonstration started." << endl; } Lab(int duration){ //Function 3 time = duration; cout << "Duration of lab is " << time << “minutes” << endl; } ~Lab(){ //Function 4 cout << "Thanks. Lab has ended." << endl; } };
Write two or more function, parameters and arguments that generates a random license plate. Your function should have approximately equal odds of generating a sequence of characters for an old license plate or a new license plate. Write a main program that calls your function and displays the randomly generated license plate.
1. Code question First, answer this code question: This is a javascript function. Please input the response of this function in the field below. function test(name, birth_year, current_year) { const age = current_year - birth_year; const response = name + " is " + age; return response;}test("alice", 1823, 1902) Enter the return value of the function.
def truth_value(integer): """Convert an integer into a truth value.""" # Convert 0 into False and all other integers, # including 1, into True if integer == 0: truth_value = False else: truth_value = True return truth_value Now, write a function that goes in the opposite direction of the truth_value() function. This new function should convert a truth value into an integer. In particular, True should be converted into 1 and False into 0. Name the new function integer_0_or_1(). All you need to include below is your definition of the function integer_0_or_1(). It will be tested automatically against relevant inputs. So include your function and nothing more.
A sphere is characterized by a single dimensions; its radius (r). The surface area of the sphere is calculated as A=4πr2 While the volume is calculated as V=43πr3 Write a program that asks the user for r and when VALID proceeds to calculate both the surface area and the volume of the sphere by calling a single function. The function's prototype is as follows: void sphereCalc(float, float *, float *); All console input and output operations are in main(). Print the area and volyme with 3 decimal places. Follow best programming practices. Use r = 3 for the screenshot. Hint: Define PI using #define PI 3.1415927
