编写汇编程序要求对数组计算平均值

编写汇编程序要求对数组计算平均值

以120, 250, 130, 178, 120, 134, 156, 178, 190, 200为例
程序如下
dseg segment
BUF db 120, 250, 130, 178, 120, 134, 156, 178, 190, 200
SUM dw ?
AVER db ?
dseg ends

cseg segment
assume ds:dseg, cs:cseg
start:
mov ax, dseg
mov ds, ax

mov cx, 10
lea bx, BUF
xor ax, ax

LoopAdd:
add al, [bx]
adc ah, 0
inc bx
loop LoopAdd

mov SUM, ax
mov bl, 10
div bl
mov AVER, al

mov ah, 4ch
int 21h
cseg ends
end start

#define arraylen 15 int main(void) { int array[arraylen ] = {0}; int i, m,min, tmp = 0,avg = 0; printf("请输入%d个整数:\r\n", arraylen ); for(i=0; i < arraylen; i++) { scanf("%d", &tmp); array[i] = tmp; } //求均值与最小值 min = array[0]; m = 0; for(i=0; i < arraylen; i++) { avg += array[i]; if(array[i] < min) { min = array[i]; m = i; } } printf("最小值:%d, index:%d\r\n", min, m); printf("均值:%d\r\n", avg / arraylen); }
