Question

C++ program, include comments stating what each part of code does please. I want to be able to understand it so I'll be more knowledgeable in the future. The program is multiple files(fibonacci.h file, fibonacci.cpp file, main.cpp file and loops_simple_data_test.cpp). After the directions I also included any starter code or comments left by my professor within the files to aide us.

Directions:

In folder 04_loops_simple_data write prototype and definition for string value - return function get_fibonacci with an int parameter that returns the fibonacci sequence up to that number. Write the required unit test(s) in folder 04_loops_simple_data_test. Main program flow: Program runs until user opts out. For each loop prompt user for a number, use number as function argument, call get_fibonacci function and display the output.

fibonacci.h

/*
	Write prototype for string value-return function get_fibonacci with an int
	parameter that returns the fibonacci sequence up to that number.
	*/

fibonacci.cpp

/*
	Write prototype for string value - return function get_fibonacci with an int
	parameter that returns the fibonacci sequence up to that number.
	DO NOT USE A RECURSIVE FUNCTION
	*/

main.cpp

//Write include statements
	//Write using statements
	/*
	Program runs until user opts out.
	For each loop prompt user for a number, use number as function argument,
	call get_fibonacci function and display the output.
	*/
	int main()
	{
	return 0;
	}

loops_simple_data_test.cpp

#define CATCH_CONFIG_MAIN // This tells Catch to provide a main() - only do this in one cpp file
	#include "catch.hpp"
	//Write includes
	/*
	Write test case for get fibonacci function with values
	10 result "0, 1, 1, 2, 3, 5, 8"
	and
	5 result "0, 1, 1, 2, 3, 5"
	*/

Note: Done accordingly. Please comment for any problem. Please Uprate. Thanks

fibonacci.h

#pragma once
#include<string>

Main.cpp

// fibonacciSequence.cpp : Defines the entry point for the console application.

#include "fibonacci.h"
#include "iostream"
using namespace std;

int getNumber(){
   int num;
   cin>>num;
   cin.clear();

       num=getNumber();

       cout<<"Do you want to check again? (y) :";
       choice=getChoice();
       if(choice!='y'){

loops_simple_data_test.cpp

// tests-main.cpp
#define CATCH_CONFIG_MAIN
#include "catch.hpp"

#include "fibonacci.h"

TEST_CASE("Testing Fibnacci") {
fibonacci testObject;

SECTION("First section, works") {
REQUIRE(obj.get_fibonacci(5)=="0 1 1 2 3 5");
}
SECTION("Second section, works") {
REQUIRE(obj.get_fibonacci(10)=="0 1 1 2 3 5 8");
}
SECTION("Second section, fails") {
REQUIRE(obj.get_fibonacci(10)=="1 1 2 3");
}
}

Output:
