汇编语言“自然数1到100的求和。并写出结果输出”

Question

各位大哥帮忙作作 啊，谢谢！

Answer 1

最简单的做法

code segment
assume cs:code
start:
mov ax,0 ;ax清零
mov bx,1 ;bx将从1循环加到100
mov cx,100 ;cx作为循环次数的控制变量
next:
add ax,bx ;ax保存加的结果
inc bx ;bx加一
loop next
mov ah,4ch ;主程序结束 返回dos
int 21h
code ends
end start

不明白再发消息给我吧 ^_^

Answer 4

main( )
{ int i, sum=0;
for( i=1; i<=100; i+ + ) sum+ = i;
printf(“sum=%d\n”, sum);
}

Answer 5

dim a,i
j=0
for i=1 to 100
a=i+i
next
response.write a
