How do you calculate 4 letter 5 letter words from a file using c programming?

To calculate the number of 4-letter and 5-letter Words from a file in C, you can open the file using fopen() and read it line by line using fgets(). For each line, use the strtok() function to split the line into Words and check the length of each Word using strlen(). Increment counters for 4-letter and 5-letter Words accordingly. Finally, close the file and print the counts.
