write a nonsensical program in assembly of about 50 lines . Include an introduction and a conclusion in which you indicate whether this is difficult or easy to come up with . 

Introduction:

Assembly is a low-level programming language used to interact directly with a computer's hardware. It is an ancient language often used for systems programming, such as writing operating systems or device drivers. In this example I will write a nonsensical program in assembly that is about 50 lines long.

Program:

ssection .data
    message db 'Hello, World!',0

section .text
    global _start

_start:
    ; print the message to the console
    mov eax, 4
    mov ebx, 1
    mov ecx, message
    mov edx, 13
    int 0x80

    ; wait for the user to press a key
    mov eax, 0
    int 0x80

    ; print a random number
    mov eax, 0
    mov ebx, 0
    mov ecx, 0
    mov edx, 0
    rdtsc
    mov ebx, eax
    mov ecx, edx
    add ebx, ecx
    mov eax, 4
    mov ecx, ebx
    mov edx, 4
    int 0x80

    ; wait for the user to press a key
    mov eax, 0
    int 0x80

    ; print the message again
    mov eax, 4
    mov ebx, 1
    mov ecx, message
    mov edx, 13
    int 0x80

    ; exit the program
    mov eax, 1
    xor ebx, ebx
    int 0x80

Conclusion:

Writing a nonsensical program in assembly isn't hard to imagine, but it can be tricky to implement because assembly is a low level programming language. The program above shows how to run the command. A message is displayed, followed by a random number and finally the same message again. This makes the program useless, as it provides no useful functionality.
