Example 1: typedef in c

typedef struct
{
  	//add different parts of the struct here
 	string username;
  	string password;
}
user; // name of struct - you can name this whatever

user example; //variable of type user

example.username = "Comfortable Caterpillar"; // username part of example variable
example.password = "password" // password part of example variable
  
if (user.username == "Comfortable Caterpillar")
{
	printf("upvote this if it helped!");
}

typedef struct Books {
   char title[50];
   char author[50];
   char subject[100];
   int book_id;
} Book;
 
int main( ) {

   Book book;
 
   strcpy( book.title, "C Programming");
   strcpy( book.author, "Nuha Ali"); 
   strcpy( book.subject, "C Programming Tutorial");
   book.book_id = 6495407;
 
   printf( "Book title : %s\n", book.title);
   printf( "Book author : %s\n", book.author);
   printf( "Book subject : %s\n", book.subject);
   printf( "Book book_id : %d\n", book.book_id);

   return 0;
