typedef struct student
{
char name[10];
char gender[4];
int age;
}STUDENT;

STUDENT students[50]

如何把结构如下的文件中的数据读取后存入数组?

[第一名]
姓名=***;
性别=***;
年龄=***;
[第二名]
姓名=***;
性别=***;
年龄=***;
.

.

希望能给出源代码,一定要C语言的,谢谢!!!

楼上，你的readini函数没有读懂啊，可否加上注释

使用FILE * fp = fopen(文件名, "r"); 打开文件
使用fgets一行行提取文本
判断文本的特征匹配到你的变量。
