题目内容 (请给出正确答案)

设有以下结构体定义及初始化,表达式p->score的结果是()。 struct node { int num; float score; }stu[2]={101,91.5,102,92.5},*p=stu; A)101 B)91.5 C)102 D)92.5

A.分析错误#B.该定义使stu[0].num=101,stu[0].score=91.5,stu[1].num=102,stu[0].score=92.5,p指向数组stu的首地址,p->score的值是stu[0].score。#C.分析错误#D.分析错误

参考答案和解析
该定义使 stu[0] .num=101, stu[0] .score=91.5, stu[1] .num=102, stu[0] .score=92.5,p指向数组 stu的首地址, p->score 的值是 stu[0] .score。
