Read input file with function

Basics

Before starting with your assignment, please go through the following basic exercises:

• w05-bsc-functions-1 #10 (closed)
• w05-bsc-functions-2 #11 (closed)

Objective

Adapt the code developed in the previous week read_input.cpp, such that the reading of the lines is done in a function in a separate file and that this returns a container of trimmed strings with the lines of a specific section in the input file. This function will be used in two different files.

Implementation

1. In the /tehpc/basics/ directory create a new file named input_file.hpp. Inside this file, implement the function name read_input_section which should, based on a file name and a section name, read the appropriate part of the file and return it as a container filled with strings. Use the code from previous week as starting point.

2. Modify read_input_test.cpp to use the function implemented in input_files.hpp. Without modifying the testing part in read_input_test.cpp, run it to test if your function works. If not, correct input_files.hpp until the test passes.

3. Modify read_input_function.cpp to use the above-mentioned function to read the input from the defined input file. Make sure that this example runs correctly.

4. Make sure that your code is well structured and commented.

Notes:

Compile and run your code by:

1. going into the tehpc/build/ folder
2. (if you have never done before) copy the file read_input_fixed.inp into the build folder.
3. (if you have never done before) copy the file read_input_test.inp into the build folder.
4. compile with the following command: g++ -Werror -Wpedantic -g -o read_input_test ../basics/read_input_test.cpp
5. run code with ./read_input_test
6. compile with the following command: g++ -Werror -Wpedantic -g -o read_input_function ../basics/read_input_function.cpp
7. run code with ./read_input_function
