Using the For loop Just like the while and the do-while loop, a for loop allows you to repeat your codes for the desired number of times. In this program, you will count the number of letters of the alphabet, digits, whitespaces and special characters in a user entered string. You need to have three separate counters for the uppercase letters, the lowercase letters and the total number of letters. Any character that is not a letter, a digit or a whitespace is a special character.
To complete this program:
• Using a suitable message, get a string from the user. Note that the string may contain more than one word.
• Inside a while loop, test each character by processing each character of the string one at a time. Think about initialization, termination and update conditions for this loop.
• If it is a letter of the alphabet, a digit or a whitespace, update appropriate counters. If it is neither of them, update the counter for the special characters. Inform the user about all the counts.
