here is the assembly lanaguage code:

section .data

prompt db 'What is your name? ',0xa

lenp equ $ - prompt ;length of prompt stringstring

helloMsg dq 'Hello '

name db ' ' ; space characters

endOfLine db '!'

section .text

global _start

_start:

; Output that information 'What is your name? '

mov eax, 4 ; write?

mov ebx, 1 ; to the standard output ?

mov ecx, prompt ; the information at memory address prompt

mov edx, lenp ; 19 bytes (characters) of that information

int 0x80 ; invoke an interrupt

; Accept input and store the user's name

mov eax, 3 ; read?

mov ebx, 1 ; from the standard input

mov ecx, name ; storing at memory location name?

mov edx, 23 ; 23 bytes (characters) is ok for my name

int 0x80

; Output that information "Hello?

mov eax, 4 ; write?

mov ebx, 1 ; to the standard output (screen/console)?

mov ecx, helloMsg ; the information at helloMsg?

mov edx, 23 ; 23 bytes (characters) is ok for my name

int 0x80

; Exit

mov eax, 1 ; sys_exit

mov ebx, 0 ; exit status. 0 means "normal", while 1 means "error"

int 0x80

I tested this program in coding ground and I cannot type anything in. what is the problem?
