#include<stdio.h>#include<conio.h>void main(){struct myStruct{int a, b;};struct myStruct myArray[5];int i;clrscr( );for(i=0;i<5;i++){myArray[i].a=i;myArray[i].b=5-i;}for(i=0;i<5;i++){printf(“%d %d %d\n”,i, myArray[i].a,myArray[i].b);}getch();}
Step 1. Complete the following program and record the results.
#include <iostream>
using namespace std;
void rect_area(float, float, float);
int main()
{
float width = 2.5, height = 3.1, area = 0.0;
___________________________ //filling by calling rect_area() method
cout << "The area in main is " << area << endl;
return 0;
}
void rect_area(float width, float height, float area)
{
area = width * height;
cout << "The area in the function is " << area << endl;
}

- What is the best statement about the following function, f1? void f1 (int i) { int j; for (j = 0; j < i; ++j); cout << ‘*’; cout << endl; } Group of answer choices The f1 function prints a star. The f1 function prints a start on the ith line. The f1 function prints a line of i-1 stars. The f1 function prints a start on each of the i lines. The f1 function prints a start on each of the i-1 lines.arrow_forwardIn C++ Please Modify the program 8-31 from page 584, 585 by adding the following: 1. Add a prototype before main() like: void bubbleSort(Circle [], int); 2. On line 21 add the following function call: bubbleSort(circle, SIZE); 3. After main() function add the definition for bublleSort() function similar to the one on page 628. Evidently you must change the Inventory data type with Circle. The example in the textbook displays all the areas in order because the input is such that will cause the in order output. Your program should display all circles in order even when the input for radii is not in any particular order. // This program uses an array of objects. // The objects are instances of the Circle class. #include <iostream> #include <iomanip> #include "Circle.h" // Circle class declaration file using namespace std; const int NUM_CIRCLES = 4; int main() { Circle circle[NUM_CIRCLES]; // Define an array of Circle objects // Use a loop to initialize the radius of each…arrow_forward1. 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 3arrow_forward

Write two Haskell functions to calculate ticket prices. Tickets for those ages 12 and under are $8.50, tickets for those between 13 and 65 are $14.50 and those older than 65 are $9.00. The second function should calculate tax – assume tax is 12%. Using function chaining to calculate the total cost. The main function should ask what type of ticket the person wants (child, adult, or senior) and call the functions that you wrote. Show the type signatures of the functions you write.arrow_forwardMark 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)arrow_forward
