Write a program in C!!!!!! that reads a text file fun.txt. Then it counts the how many times each letter (within the alphabet) is occurring in the file. It also counts how many times each digit is also occurring in the file. Finally, your code should also count how many times the word "no" is occurring in the file. Then your program should show the results in console as well as write the result into a file result.txt. The output has to be in the following format.Note that if a letter is upper case, you might need to convert it into lowercase. For example, for the given fun.txt file you will get the the following result: a 8 b 2 c 6 d 14 e 22 f 1 g 0 h 11 i 12 j 0 k 1 l 1 m 6 n 10 o 17 p 2 q 0 r 7 s 6 t 17 u 4 v 2 w 8 x 0 y 2 z 0 === 0 0 1 2 2 1 3 1 4 0 5 0 6 1 7 0 8 0 9 0 no count is 2Hint: Use an int array of size 26 to store your letter counts and use another array for size 10 to store the digit counts
