Assembly Program to Count Characters in a String
The program will prompt the user to input a string and will count the number of characters present in that string. The program will not count white spaces as white spaces are not characters.
The program takes a string and stores the string in STRING and will start iteration if there is a white space the program will continue without incrementing CHARACTERS and if there is a character the program will increment CHARACTERS. After counting the characters the program simply prints the number of characters.
