Question

Write a MASM program that computes the sum of the integers from 1 to N where N is a positive integer. Use the equal sign directive to define N. Save the sum in the EAX register. You must use loops.

For example,

1 = 1

1 + 2 = 3

1 + 2 + 3 = 6

1 + 2 + 3 + 4 = 10

1 + 2 + 3 + 4 + 5 = 15

Answer 1

#INCLUDE io.h

Cr EQU 0ah

Lf EQU 0dh

data SEGMENT

p_n DB cr, lf, 'Enter n: ',0

p_num DB lf, 'Enter a number: ',0

p_sun DB cr, lf, 'The sum is: ',0

tmpstr DW 40 DUP (?)

data ENDS

code SEGMENT

ASSUME cs:code, ds:data

start: mov ax, data

mov ds, ax

output p_n

inputs tmpstr, 10

atoi tmpstr

mov dx, ax

mov bx, 0

n_ip: output p_num

inputs tmpstr, 10

atoi tmpstr

add bx, ax

dec dx

jnz n_ip

output p_sum

itoa tmpstr, bx

output tmpstr

quit: mov al, 00h

mov ah, 4ch

int 21h

code ENDS
