题目：程序通过定义学生结构体变量，存储学生的学号、姓名和3门课的成绩。函数fun的功能是：将形参a所指结构体变量中的数据赋给函数中的结构体变量b，并修改b中的学号和姓名，最后输出修改后的数据。例如：a所指变量中的学号、姓名和三门课的成绩依次是：10001、"ZhangSan"、95、80、88，则修改后输出b中的数据应为：10002、"LiSi"、95、80、88。#include #include struct student{long sno;char name[10];float score[3];};void fun(struct student a){struct student b;int i;/*****SPACE/b = 【①】;b.sno = 10002;/SPACE/strcpy(【②】, "LiSi");printf("\nThe data after modified :\n");printf("\nNo: %ld Name: %s\nScores: ",b.sno, b.name);for (i=0; i<3; i++)/SPACE*****/printf("%6.2f ", b.【③】);printf("\n");}main(){struct student s={10001,"ZhangSan", 95, 80, 88};int i;printf("\n\nThe original data :\n");printf("\nNo: %ld Name: %s\nScores: ",s.sno, s.name);for (i=0; i<3; i++)printf("%6.2f ", s.score[i]);printf("\n");fun(s);}
