C programming language help. I have attached the "demo program"(which uses dynamic memory allocation). The demo program stares an array of integers, but I need to make an array of characters. Please help me write the code and please separate the header files(.h) and source files(.c). Also, please comment the code if necessary. Thank you

In this homework assignment, you will write a program to solve a word search puzzle. An example puzzle is shown below, along with the search words. The goal of the puzzle is to find each search word. The trick is that the search words are surrounded by random characters. Further, the search words can appear forwards, backwards, horizontally, vertically, or diagonally (in either direction)!

This program will read a puzzle from a text file saved to disk. The first line of the file should contain the dimensions of the grid (rows, then columns). On subsequent lines, the actual grid of characters should be provided. The input may contain upper and lower case characters, but you should convert them all to lower case when you read them.
