C语言结构体(Struct) 前面的教程中我们讲解了数组(Array),它是一组具有相同类型的数据的集合。但在实际的编程过程中,我们往往还需要一组类型不同的数据,例如对于学生信息登记表,姓名为字符串,学号为整数,年龄为整数,所在的学习小组为字符,成绩为小数,因为数据类型不同,显然不能用一个数组来存放。 在C语言中,可以...
在定义结构体数组时进行初始化,为清晰起见,将每个学生的信息用一对花括号包起来,这样做,阅读和检查比较方便,尤其当数据量多时,这样是有好处的。 C语言使用结构体数组求五个人的平均成绩 #include <stdio.h> struct{ char *name; //姓名 float score; //成绩 }array[] = { //结构体数组 {"张三",145.0}...
Using a struct array in C allows you to store and process collections of structured data. With the flexibility of dynamic memory allocation, you can create struct arrays of any size according to your program's requirements. Understanding and utilizing struct arrays in C will help you build compl...
