法律研究解释 C 语言中结构变量的访问
结构是一种用户定义的数据类型，用于存储不同类型的数据集合。
结构与数组类似。唯一区别在于数组存储相同类型的数据，而结构存储不同类型的数据。
struct 关键字用于声明结构。
结构中的变量是结构的成员。
结构可以声明为以下形式 −
Struct structurename{
//member declaration
};示例
以下是 C 程序中访问结构变量的内容 −
struct book{
int pages;
float price;
char author[20];
};
Accessing structure members in C
#include<stdio.h>
//Declaring structure//
struct{
char name[50];
int roll;
float percentage;
char grade[50];
}s1,s2;
void main(){
//Reading User I/p//
printf("enter Name of 1st student : ");
gets(s1.name);
printf("enter Roll number of 1st student : ");
scanf("%d",&s1.roll);
printf("Enter the average of 1st student : ");
scanf("%f",&s1.percentage);
printf("Enter grade status of 1st student : ");
scanf("%s",s1.grade);
//Printing O/p//
printf("The name of 1st student is : %s
",s1.name);
printf("The roll number of 1st student is : %d
",s1.roll);
printf("The average of 1st student is : %f
",s1.percentage);
printf("The student 1 grade is : %s and percentage of %f
",s1.grade,s1.percentage);
}输出
执行上述程序后，生成以下结果 −
enter Name of 1st student: Bhanu enter Roll number of 1st student: 2 Enter the average of 1st student: 68 Enter grade status of 1st student: A The name of 1st student is: Bhanu The roll number of 1st student is: 2 The average of 1st student is: 68.000000 The student 1 grade is: A and percentage of 68.000000
