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 done
num2g:
mov eax,num2
cmp eax,num3
jl num3g
jmp done
num3g:
mov eax,num3
done:
call writeint
main endp
end main
运行结果:
