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中的数据进行修改,把修改后的数据作为函数值返回主函数进行输出。例如:若传给形参a的数据中学号、姓名和三门课的成绩依次是:10001、"ZhangSan"、95、80、88,修改后的数据应为:10002、"LiSi"、96、81、89。#include #include struct student{long sno;char name[10];float score[3];};struct student fun( ____ ){int i;a.sno = 10002;strcpy( ____, "LiSi");for (i=0; i<3; i++)____ += 1;return a;}main(){struct student s={10001,"ZhangSan", 95, 80, 88}, t;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");t = fun(s);printf("\nThe data after modified :\n");printf("\nNo: %ld Name: %s\nScores: ",t.sno, t.name);for (i=0; i<3; i++)printf("%6.2f ", t.score[i]);printf("\n");}
