    Hello - I am new to assembly language and just started to learn- I have a question - I have to get input(string, integer and double) from the user and store and print it on screen - but for some reason my code is showing weird o/p - double/string doesn't work.

    Could somone guide me please?

    prompt1: .asciiz "\n Please Input a Double value = "
    prompt2: .asciiz "\n Please Input a Float value = "
    prompt3: .asciiz "\n Please Input a String value = "
    result: .asciiz " The sum of the integers NEW from 1 to N is "
    result1: .asciiz " You have enter : "
    bye: .asciiz "\n **** Have a good day ****"

    read and store a string

    Code:
    .data
    S: .space [COLOR=DarkRed]20[/COLOR] #20 characters
    ...........
        la $a0, S        #store input string into S
        li $a1,[COLOR=DarkRed]20[/COLOR]       
        li $v0,8
        syscall
    .............
