Write an EXE program that accepts a string from the keyboard, counts the number

Question

Write an EXE program that accepts a string from the keyboard, counts the number of capital and small alphabets, digits, and other symbols excluding spaces and tabs , and echoes the string and its count information on the screen. can we do it using jmp, loop cmp functions ? I have the code where in they tried to map the whole ascii table by creating a table in data segment as below. Can i get it without using table but just comparing , looping using asciii values. Thank you
