結構體是使用者定義的資料類型，用於儲存不同資料類型的資料的集合。
結構體類似於陣列。唯一的區別是數組用於存儲相同的資料類型，而結構體用於存儲不同的資料類型。
關鍵字struct用於聲明結構體。
裡面的變數結構體是結構體的成員。
結構體可以宣告如下-
Struct structurename{
//member declaration
};#以下是存取結構體變數的C 程式-
現場演示
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</p><p>",s1.name);
printf("The roll number of 1st student is : %d</p><p>",s1.roll);
printf("The average of 1st student is : %f</p><p>",s1.percentage);
printf("The student 1 grade is : %s and percentage of %f</p><p>",s1.grade,s1.percentage);
}執行上述程式時，會產生以下結果-
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
