Definition and use of structure arrays

Preface

If you are not familiar with the use of structure variables, you can first read this article by the blogger [C Language] Structure Variable Definition, Initialization, and Usage

 

1. Define the structure array and initialize it

  
  
   
   
//First declare the structure type
struct students
{
char name[ 20];
int age;
};

//Define the structure array and initialize it
struct students stu[ 3]={ "Allen", 18, "Smith", 19, "Grace", 18};
  
  
   
   

In order to improve code readability, you can also use { } to group data during initialization (equivalent to the above code)

struct students stu[NUM]={
    
    {
    
    "Allen",18},{
    
    "Smith",19},{
    
    "Grace",18}};
  
  
   
   

 

2. Reference structure array

  
  
   
   
printf ( "name age\n\n" );
//Loop output
for( int i= 0;i< 3;i++)
{
printf( "%s %d\n\n",stu[i].name,stu[i].age);
}
  
  
   
   

The result is as follows:

The complete test code is as follows:

  
  
   
   
#include <stdio.h>

# define NUM 3

int main()
{
//Declare the structure type
struct students
{
char name[ 20];
int age;
};

//Initialize the structure array
struct students stu[NUM]={ { "Allen", 18},{ "Smith", 19},{ "Grace", 18}};

//Output
printf ( "name age\n\n" );
for( int i= 0;i<NUM;i++)
{
printf( "%s %d\n\n",stu[i].name,stu[i].age);
}

return 0;
}
  
  
   
   

The result is as follows:
