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. 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) 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 least squares line is determined as follows: See Figure 1 The function does not return any value to the calling statement. void WriteFile (double, double); Write a function that saves the formula of the least squares line to a text file. 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. See the example output for the file contents. See figure 2 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.

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.

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)

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 least squares line is determined as follows:

See Figure 1

The function does not return any value to the calling statement.

void WriteFile (double, double);

Write a function that saves the formula of the least squares line to a text file. 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. See the example output for the file contents.

See figure 2

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.
