Simplified C Programs

17. Program

#include 

#include 

#include 

typedef struct Books

{

   char  title[50];

   char  author[50];

   char  subject[100];

   int   book_id;

} Book;

int main( )

{

clrscr();   

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;

   getch();

}

Output

Book  title : C Programming

Book  author : Nuha Ali

Book  subject : C Programming Tutorial

Book  book_id : 6495407

18. Program

#include 

#include 

#define TRUE  1

#define FALSE 0

int main( )

{

   printf( "Value of True : %d\n", True);

   printf( "Value of False : %d\n", False);

   return 0;

   getch();

}

Output

Value of True : 1

Value of False : 0

19. Program

#include 

#include 

int main( )

{

   int c;

   printf( "Enter a value :");

   c = getchar( );

   printf( "\nYou entered: ");

   putchar( c );

   return 0;

   getch();

}

Output

Enter a value : this is test

You entered: t

20. Program

#include 

#include 

int main( )

{

   char str[100];

   printf( "Enter a value :");

   gets( str );

   printf( "\nYou entered: ");

   puts( str );

   return 0;

 getch();

}

Output

Enter a value : this is test

You entered: This is test
