C语言描述该程序流程：

#include <stdio.h>
int main()
{int a=10,b=20,c=15;//scanf("%d %d",&a,&b);if(a>=b){if(a>=c){printf("%d",c);}else{printf("%d",a);}}else{if(b>=c){printf("%d",b);}else{printf("%d",c);}}}

汇编语言：

include irvine32.inc
.data
num1 dword 10
num2 dword 20
num3 dword 15
max   dword ?
.code 
main proc
mov eax,num1
cmp eax,num2
jl num2g ;如果num1比num2小，则对num2和num3做比较找最大值
cmp eax,num3 ;否则num1和num3做比较找最大值
jl num3g
jmp donenum2g:
mov eax,num2
cmp eax,num3
jl num3g
jmp donenum3g:
mov eax,num3done:
call writeint
main endp
end main

运行结果：
