结构体之成绩记录

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<stdlib.h>

struct Person

{

char StudentID[5];

char name[20];

int Languagescores;

int Mathgrades;

int Englishscores;

};

void input(struct Person* T) //指向结构的指针

{

scanf("%s %s %d %d %d", &T->StudentID, &T->name, &T->Languagescores, &T->Mathgrades, &T->Englishscores);

}

void print(struct Person* per)//指向结构的指针

{

printf("%s,%s,%d,%d,%d\n", per->StudentID, per->name, per->Languagescores, per->Mathgrades, per->Englishscores);

}

int main()

{

int a = 0;

scanf("%d", &a);

struct Person* per, * p;

per = (struct Person*)malloc(sizeof(struct Person) * a);  //动态申请内存

if (per == NULL)

{

printf("内存分配失败\n");

return 0;

}

p = per;           //指针数组

for (int i = 0; i < a; i++)

input(p + i);

for (int i = 0; i < a; i++)

print(p + i);

return 0;

}

//上次代码有些问题，这次修正。
