In this coursework, you are not allowed to change the name of input file. In the marking, we change the numbers in the input file so that do not calculate the solutions manually and report these. You are not allowed to use file output. You program should just read the input file and display the solutions. You should use Visual Studio 2015. If you did not follow these instructions, you will be penalized. Write 3 programs and upload each program (cpp file) to Blackboard (Go to Blackboard 16/17-EN2008 Coursework. For instance, to upload the program of Task1, click CW1Task1 then click Browse My Computer and upload your program cpp file) of Task1. You can upload file several times for each question. But we mark only the latest attempt. If you have questions on the coursework, please raise in the next lab session. Task1 [6 points] Create a program that reads coordinates of four points (A, B, C and D) in 2D from the file (week8triangle.txt) and reports the user the followings: 1: Each length of sides of the triangle of points A, B and C 2: Total length of sides of the triangle Task2 [7 points] Based on the program of Q1 (use the same input file), create a program that reports 1: Angles of A, B and C In degrees 2: Area of the triangle
