我没有使用结构获得任何输出

Question

我应该打印平均分最高的学生的名字，但我的程序没有输出任何东西，有什么解决办法吗？当我尝试在 printf 中将 %s 更改为 %c 时，我成功获得了输出，但显然只有第一个字符如何输出整个字符串？

#include<stdio.h>
#include "LV2 Z2.h"
int main()
{
    int n,i;
    struct student students[40];
    
    scanf("%d",&n);
    for(i=0;i<n;i++)
    {
    printf("Enter the name:\n");
    scanf("%s",&students[i].name);
    printf("Enter the surname:\n");
    scanf("%s",&students[i].surname);
    printf("Enter the ID:\n");
    scanf("%d",&students[i].studentID);
    printf("Enter the average:\n");
    scanf("%f",&students[i].average);
    printf("Enter the date:\n");
    scanf("%s",&students[i].date);
        
        
    }
    float max = 0;
    int bestStudent = 0;
    for(i=0;i<n;i++)
    {
     if(students[i].average > max) {
    max = students[i].average;
    bestStudent = i;
    }
    }
    printf("Student : %s %s ima najbolji prosjek",students[bestStudent].name,students[bestStudent].surname);
    return 0;
}



struct student 
{
    char name[100];
    char surname[100];
    int studentID;
    float average;
    char date[100];
    
};

没有你的头文件，我运行你的程序。我不得不将您的结构定义移至 main 之上，以便 main 能够识别它。否则，它不会编译。您之前是否在头文件中定义了结构，但为了向我们展示，您只是将其移至 main 中？如果是这样，那将导致您的程序无法运行。

我还更改了涉及 %s 的 scanf()。数组的名称计算为第一个元素的地址，即

int myArray[20]; // myArray evaluates as &myArray[0]

所以，删除所有涉及 %s 的 scanf 的 & 符号。

进行这些更改后，我运行你的程序似乎运行良好。

#define _CRT_SECURE_NO_WARNINGS

#include<stdio.h>

struct student
{
    char name[100];
    char surname[100];
    int studentID;
    float average;
    char date[100];

};

int main()
{
    int n, i;
    struct student students[40];

    scanf("%d", &n);
    for (i = 0; i < n; i++)
    {
        printf("Enter the name:\n");
        scanf("%s", students[i].name);
        printf("Enter the surname:\n");
        scanf("%s", students[i].surname);
        printf("Enter the ID:\n");
        scanf("%d", &students[i].studentID);
        printf("Enter the average:\n");
        scanf("%f", &students[i].average);
        printf("Enter the date:\n");
        scanf("%s", students[i].date);


    }
    float max = 0;
    int bestStudent = 0;
    for (i = 0; i < n; i++)
    {
        if (students[i].average > max) {
            max = students[i].average;
            bestStudent = i;
        }
    }
    printf("Student : %s %s ima najbolji prosjek", students[bestStudent].name, students[bestStudent].surname);
    return 0;
}
