解釋 C 語言中結構變數的訪問
結構是一種使用者定義的資料型別,用於儲存不同型別的資料集合。
結構與陣列類似。唯一區別在於陣列儲存相同型別的資料,而結構儲存不同型別的資料。
struct 關鍵字用於宣告結構。
結構中的變數是結構的成員。
結構可以宣告為以下形式 −
Struct structurename{
//member declaration
};示例
以下是 C 程式中訪問結構變數的內容 −
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);
}輸出
執行上述程式後,生成以下結果 −
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
