Version 3: Cone is a three-dimensional structure having a circular base where a set of line segments, connect all of the points on the base to a common point called apex. A cone can be seen as a set of non-congruent circular discs that are stacked on one another such that ratio of the radius of adjacent discs remains constant. The area is a cone is computed as A = (s sin(x) )² where, "s" is the slant and "x" is the angle in radian. Write a C++ program that computes the area A of Cone by reading its parameter from a text file "input.txt". Each line of the file represents the Cone name, the slant "s" and the angle "x" of a Cone, respectively. The program should read each line to compute the area A of each Cone. It should also display the minimum computed area. Your program should implement the following functions: Area(): This function receives the values of "s", and "x" then computes and returns the value of area A. Print(): This function receives the name of Cone and the computed area…
Transcribed Image Text Problem 3) Create a text file that contains the following information: John Doe 2005 124.80 36 Note that the fist line represents the name of the client, the second line represents the year in which the client started an account with this insurance company. The third line represent the monthly payment for the insurance. The fourth line represents the number of months left in the insurance policy. Write a C++ program that will read this file and will display the client's name, the number of years for which this client has been with the company, and the remaining amount they have to pay

JAVA PROGRAMMINGIf Statements - Program #1Ms. Monroe is an Income Tax Practitioner who operated a service that prepares income taxforms. Her fees are based on the type of form filed and yearly income.Program Specifications:a. Create a folder named If Program 01. Save the Java file as TaxPrep.b. Input consists of the customer's name, the form type (1 - short form; 2 - long form), andthe yearly income. Sample input is illustrated on page 2. You will enter the input from thekeyboard. Input prompts should be very specific. When inputting the form type makesure that you display 1 – Short Form or 2 – Long Form. The user needs to know what toenter. This program will process one record and only one record at a time.c. The basic fee is $100 for a short form (form type of 1) or $200 for a long form (form typeof 2). The income fee is based on the yearly income. If the yearly income is less the$50,000, the income fee is the same as the basic fee. If the yearly income is $50,000 ormore, the income…

C PROGRAMMING ONLY, Having trouble with this step as well, thank you so much for the help! NO IOSTREAM.H OR CACIO.H PLEASE I CANT USE THOSE HEADERS. Modify the given Script to meet the following conditions: Create a C script that will: 1) Read a text file “Data.txt”. The numbers in the first column of Data.txt are a1’s, thesecond column are a2’s, the third column are y(0)s and the fourth column are y’(0)s. 2) Use these numbers to find the Zero-Input Responses. (So, the user will not type inthose numbers. Your program should read those values from the Data.txt file automatically.Then, your program should compute the roots and required coefficients.) 3) Save the result (Coefficients) on “Result.txt” Here is the format for Result.txt;1) The first column indicates whether the system has nonrepeating real roots, repeatingreal roots, or complex conjugate roots. Use 1 for nonrepeating real roots, 2 for repeatingreal roots, and 3 for complex conjugate roots.2) The second column should be used…
