#include<stdio.h>
int g(int x ,int y)

    return x+y;}

int f (int x,int y)
{
    {
        static int x=2;
        if(y>2)
        {x=x*x;y=x;}
        else y=x+1;
    }
    return x+y;
}
main()
{
    int a=3;
    printf("%d\n",g(a,2));
    printf("%d\n",f(a,3));
    printf("%d\n",f(a,2));
}

谢谢 我最后的x的值用错了  原来外面一直是3啊
