Write a C/C++ program that calculates the least squares line for two sets of values. The program consists of several functions which are described below. The first function you need to write: int ReadFile (int *, int *); Write a function that reads the contents of a text file (Data1.txt) into two separate integer arrays. The function receives two integer pointers to arrays as parameters. The contents of the text file that is attached is structured as follows: Each line in the file contains two values that are separated by a comma. The values on the left of the comma, are stored in one array and the values on the right side is stored in the other array. The number of lines that are read from the file and stored in the arrays are returned to the calling statement. Tip: a single fscanf can read into multiple variables. Ex. the statement fscanf(fp, "%s %s\n", name,surname) will read the line John Doe and save the name and surname separately. (Note the space between %s and %s indicates that there is a space in the data between the two strings to be captured) The second function you need to write: void LeastSquaresLine (int *, int *, double *, double *, int); Write a function that determines the elements a0 and a1 of the least squares line for the contents of two arrays. The function receives two integer pointers for arrays (x and y), two reference parameters for the return of a0 and a1, and the length of the arrays. *The calculations you will need to determine the Least squares line is attached in the image below.* The third function you need to write: void WriteFile (double, double); Write a function that saves the formula of the least squares line to a text file(Output.txt). The function receives two real values for a0 and a1 after which the formula is saved in the form y = mx + c where m = a0 and c = a1. The example of the output file is attached in the image below: If the file can not be opened for writing an appropriate error message is to be displayed. The function does not return any value to the calling statement int main (); Implement the above functions in the main function to complete the program. Summary: You need to write 3 functions(int ReadFile (int *, int *); void LeastSquaresLine (int *, int *, double *, double *, int); void WriteFile (double, double);) and call them in your main function. The ReadFile reads the Data1.txt file. The LeastSquaresLine function uses the data it read from ReadFile to calculate the least square line with the calculations shown in the image below. The WriteFile function creates a new file called Output.txt and rewrites the least square line in the Output.txt file like shown in the output example in the image below. The Data1.txt file you need to use is shown below, you need to copy that values into your notepad on your computer and save it as Data1.txt. Save the Data1.txt file in the same file you save your code in order for it to work.
Write a C/C++ program that calculates the least squares line for two sets of values. The program consists of several functions which are described below.
The first function you need to write:
int ReadFile (int *, int *);
Write a function that reads the contents of a text file (Data1.txt) into two separate integer arrays. The function receives two integer pointers to arrays as parameters.
The contents of the text file that is attached is structured as follows: Each line in the file contains two values that are separated by a comma. The values on the left of the comma, are stored in one array and the values on the right side is stored in the other array.
The number of lines that are read from the file and stored in the arrays are returned to the calling statement.

The example of the output file is attached in the image below:

int main ();
Implement the above functions in the main function to complete the program.
