Write a C program to count the number of alphabets (upper-case and lower-case) and the number of words in a string defined in the program. Please do not use the library functions to determine if a character is a letter. [Hint- You can compare with ASCII values.] For demonstration purpose, please sure that your output looks like following: String: Hello! Welcome to CPE325. Its a great day, isnt it? Contains: The string contains 35 alphabetic characters and 10 words.
