Question

18.1 Lab Lesson 11 (Part 1 of 1) Part of lab lesson 11 There in one part to lab lesson 11. The entire lab will be worth 100 points. Lab lesson 11 part 1 is worth 100 points For part 1 you will have 80 points if you enter the program and successfully run the program tests. An additional 20 points will be based on the style and formatting of your C++ code. Style points The 20 points for coding style will be based on the following guidelines: • Comments at the start of your programming with a brief description of the purpose of the program. • Comments throughout your program • Proper formatting of your code (follow the guidelines in the Gaddis text book, or those used by your CS 1336 professor) . If you have any variables they must have meaningful names. Development in your IDE For lab lesson 11 you will be developing your solutions using an Integrated Development Environment (IDE) such as Visual Studio, Code::Blocks or Eclipse. You should use whatever IDE you are using for your CS 7336 class. Once you have created and tested your solutions you will be uploading the files to zyBooks/zyLabs. Your uploaded file must match the name specified in the directions for the lab lesson. You will be using an IDE and uploading the appropriate files for this and all future lab lessons. The filename for your source file must be lesson 17part1.cpp. You will need to develop and test the program in your IDE. Once you are satisfied that it is correct you will need to upload the source file to zyBooks/zyLabs, and submit it for the Submit mode tests. If your program does not pass all of the tests you need to go back to the IDE, and update your program to fix the problems you have with the tests. You must then upload the program from the IDE to zyBooks/zylabs again. You can then run the tests again in Submit mode. When running your program in Submit mode it is very important that you look at the output from all of the tests. You should then try and fix

Answer 1

Note: I developed this program using the DEVC++ editor.

Could you plz go this code and let me know if u need any changes in this.Thank You

We have to store the input file in "bin" folder C:\Program Files (x86)\Dev-Cpp\MinGW64\bin As I installed Dev C++ in C Drive this is path. If u have installed Dev C++ in another drive just check for the "bin" in that drive Ex: Suppose I have to read the data from "testscores.txt", We have to copy that file in "bin" folder of Dev C++ like as below. > This PC > Windows (C:) > Program Files (x86) > Dev-Cpp > MinGW64 > bin Name Date modified Type Size testscores 10/28/2019 2:02 A...
