如何用结构体数组实现成绩的输入、输出、求平均成绩和最高成绩？
#include #define ARR_SIZE 80 #define NAME_SIZE 30 typedef struct grade { int id; char name[NAME_SIZE]; ? ?float score; } grade_t; int gStudentNum = 0; void inputScores(grade_t *pScores); void outputScores(grade_t *pScores); float getAverageScore(grade_t *pScores); float getMaxScore(grade_t *pS...全部
#include #define ARR_SIZE 80 #define NAME_SIZE 30 typedef struct grade { int id; char name[NAME_SIZE]; ? ?float score; } grade_t; int gStudentNum = 0; void inputScores(grade_t *pScores); void outputScores(grade_t *pScores); float getAverageScore(grade_t *pScores); float getMaxScore(grade_t *pScores); int main() { ? ?grade_t student_grades[ARR_SIZE] = {0}; ? ? ? ?inputScores(student_grades); ? ?outputScores(student_grades); ? ?printf("Average Score: %。
2f, Max Score: %。1f
", getAverageScore(student_grades), getMaxScore(student_grades)); ? ?return 0; } void inputScores(grade_t *pScores) { ? ?int i; int studentNum; input: printf("请输入要记录成绩的人数:"); scanf("%d", &studentNum); if (studentNum > 0) { ?gStudentNum = studentNum; ? ? for (i = 0; i maxScore) ?{ ? maxScore = pScores[i]。
score; ?} } return maxScore; } 也可以不用指针，像下面这样：#include #define ARR_SIZE 80#define NAME_SIZE 30typedef struct grade{ int id; char name[NAME_SIZE]; float score;} grade_t;int gStudentNum = 0;grade_t student_grades[ARR_SIZE] = {0};void inputScores(grade_t pScores[]);void outputScores(grade_t pScores[]);float getAverageScore(grade_t pScores[]);float getMaxScore(grade_t pScores[]);int main(){ inputScores(student_grades); outputScores(student_grades); printf("Average Score: %。
2f, Max Score: %。
1f
", getAverageScore(student_grades), getMaxScore(student_grades)); return 0;}void inputScores(grade_t pScores[]){ int i; int studentNum;input: printf("请输入要记录成绩的人数:"); scanf("%d", &studentNum); if (studentNum > 0) { gStudentNum = studentNum; for (i = 0; i 追答 : 第二行include后少了 。收起
