Illustrate your knowledge of C-Programming by writing a user defined function to solve the quadratic equation. Function will take a, b and c as input and compute and return both the roots of the quadratic equation. If roots are imaginary, function will return -1 as the error value for both the roots. In main (), ask the user to enter values of a, b and c and call the user defined function. At the end, main ) will display both the roots returned by the function on screen. -6t/b2 –4ac x = 2a

(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.
(Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.
(Numerical) Heron’s formula for the area, A, of a triangle with sides of length a, b, and c is A=s(sa)(sb)(sc) where s=(a+b+c)2 Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of sand[s(sa)(sb)(sc)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A=1. The value of A should be returned by the function.
***Coded in Dr Racket Scheme ONLY (.rkt file)*** #lang racket ***Will downvote if coded in another language*** Write two recursive functions that calculates the leibniz series to 100 terms.In the first version, determine the sign of each term with a named subprogramThe second version of the function that uses lambda instead of a named subprogram.
(C Language) Write a recursive function called DrawTriangle() that outputs lines of '*' to form a right side up isosceles triangle. Function DrawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting. Hint: The number of '*' increases by 2 for every line drawn.
Solve the problem in C++ (Geometry: find the bounding rectangle) A bounding rectangle is the minimum rectangle that encloses a set of points in a two-dimensional plane, as shown in Figure 11.9d. Write a function that returns a bounding rectangle for a set of points in a two-dimensional plane, as follows: const int SIZE = 2; Rectangle2D getRectangle(const double points[][SIZE]); Write another function that returns a pointer to the bounding rectangle as follows: Rectangle2D* getRectanglePointer(const double points[][SIZE]); The Rectangle2D class is defined in Programming Exercise 11.9. Write a test program that prompts the user to enter five points and displays the bounding rectangle’s center, width, and height. Sample Run Enter five points: 1.0 2.5 3 4 5 6 7 8 9 10 The bounding rectangle’s center (5.0, 6.25), width 8.0, height 7.5

PLEASE CODE THIS IN C AND NOT C++. ONLY USE IF/CASE AND USER-DEFINED FUNCTIONS. PLEASE DO NOT USE LOOPS,STRUC, AND POINTERS. PLEASE ONLY DECLARE AND CALL VARIABLES IN THE MAIN FUNCTION, EVERYTHING ELSE IS IN A DIFFERENT USER-DEFINED FUNCTION. PLS CHECK IF IT WORKS TOO.
