how to use struct in c code example
Example 1: struct in C
#include
#include
struct Student{
long int rollNo;
int age;
char name[50];
int totalMarks;
};
int main(){
struct Student s1;
//accessing members of the struct
s1.rollNo = 1232234643;
s1.age = 10;
char s[]="Jonathan";
strcpy(s1.name,s);
s1.totalMarks = 450;
printf("RollNumber: %d \nName: %s \nTotal Marks: %d",s1.rollNo,s1.name,s1.totalMarks);
return 0;
}
Example 2: struct in c
typedef struct {
char cognome[30];
char nome[20];
int voto;
}alunno;
Example 3: structs in c
#include
#include
struct book{ //this is like making a datatype of type book
//these are the fields
char name[50];
char author[50];
char ISBN[11];
};
int main(){
struct book book1; //making an instance of book called book1
/*
normally to store integers in a struct we can do something like
book1.number_of_pages = 22; which is correct
however with character arrays we need to use the strcpy
function
*/
strcpy(book1.name, "james and the giant tatti");
strcpy(book1.author, "Krishan Grewal");
strcpy(book1.ISBN, "12345678987");
printf("book name: %s\n", book1.name);
printf("book author: %s\n", book1.author);
printf("book ISBN: %s\n", book1.ISBN);
return 0;
}
Example 4: struct in c
// dichiarazione della struct
struct libro
{
char titolo[100];
char autore[50];
int anno_pubblicazione;
float prezzo;
};
//dichiarazione dell'istanza biblio
struct libro biblio;

The basic structure
Example 6: Structure of Structs in c
struct [structure_tag]
{
//member variable 1
//member variable 2
//member variable 3
...
}[structure_variables];
