Develop a simple C program that reads and writes from a file and uses loops and arrays.

Instructions
Files allow you to store data persistently. In this task you will take a simple c file reading program and modify it to read multiple lines using a loop, store each line as an element in an array, then print the lines to the Bash terminal screen.
To explore this topic, we will create a C program that will:
■ Open a file and read in the number of lines in the file.
■ Loop according to the number of lines to read in each line.
■ Store each line in an array.
■ Print out the lines from the array to the terminal

1. The integer read from the first line of the file should indicate the number of text lines that follow. Your program should then loop reading one line after another into an array of my_string (or *char[]’s) until all the text lines have been read in. Call a procedure, passing in the array and the number of lines, that prints out to the terminal all the text lines that read from the file.

2. Comment out the write_lines() procedure. Instead you will need to create a text file (mytestfile.dat) with a number on the first line (to indicate the following number of text lines) and then lines of text. Use notepad or Sublime Text to create the file.

int numberOfLines;
    my_string lineArray[20];
    FILE *file_ptr;
    int i;   
    // Steps:
    // 1: Open the file
    file_ptr = fopen("mytestfile.dat", "r");

    //2. Read in the number of text lines in the file.
    fscanf(file_ptr, "%d", &numberOfLines);
    //       3. Loop reading each line of line text into an array until
    //       all the lines have been read.
    for (i = 0; i < 20 && i < numberOfLines; i++) {...
