【36】假定已建立以下链表结构, 且指针p和q已指向如图所示的结点:

则以下选项中可将q所指结点从链表中删除并释放该结点的语句组是

#include <string.h>
struct A
{
    int a;
    char b[10];
    double c;
};

    struct A a = { 1001,"ZhangDa", 1098.0 };
    f(a);
    printf("%d,%s,%6.1f\n", a.a, a.b, a.c);
}
void f(struct A t)
{
    t.a = 1002;
    strcpy(t.b,"ChangRong");
    t.c = 1202.0;
}

#include <stdio.h>
#define N 5
#define M N + 1
#define f(x)(x * M)
void main()
{
    int  i1, i2;
    i1 = f(2);
    i2 = f(1 + 1);
    printf("%d  %d\n", i1, i2);
}

#include <stdio.h>
void main()
{
    int a = 5, b = 1, t;
    t = (a << 2) | b;
    printf("%d\n", t);
}
