Write a C program that reads from a file and provides a summary of how many times a specified set of words occurs.

Important: words are separated by spaces, commas, periods, or newlines.

Important: for string parsing, you may use the functions strlen and strncmp$,$ but no other string functions from the C library. $($Do not use strtok, sscanf, scanf, strstr$,$ etc.$)$

For file I$/$O$,$ you will likely be using the functions we have discussed in class $($fopen$,$ fread, ftell, fseek$).$
