在C编程语言中,结构最常见的用法是结构数组。
要声明结构数组,首先必须定义结构,然后可以定义该类型的数组变量。
例如,结构书b [10];//“ book”类型的结构数组中的10个元素
下面给出的是C程序,用于接受和打印3名学生关于一系列结构的详细信息-
#include <stdio.h> #include <string.h> struct student{ int id; char name[30]; float percentage; }; int main(){ int i; struct student record[2]; // 1st student's record record[0].id=1; strcpy(record[0].name, "Bhanu"); record[0].percentage = 86.5; // 2nd student's record record[1].id=2; strcpy(record[1].name, "Priya"); record[1].percentage = 90.5; // 3rd student's record record[2].id=3; strcpy(record[2].name, "Hari"); record[2].percentage = 81.5; for(i=0; i<3; i++){ printf(" Records of STUDENT : %d \n", i+1); printf(" Id is: %d \n", record[i].id); printf(" Name is: %s \n", record[i].name); printf(" Percentage is: %f\n\n",record[i].percentage); } return 0; }输出结果
执行以上程序后,将产生以下结果-
Records of STUDENT : 1 Id is: 1 Name is: Bhanu Percentage is: 86.500000 Records of STUDENT : 2 Id is: 2 Name is: Priya Percentage is: 90.500000 Records of STUDENT : 3 Id is: 3 Name is: Hari Percentage is: 81.500000
