Explanation / Answer

/*

This program in compiled using GCC Compiler in Dev-C++

Question no is added in bold as comment in the program for ease of understanding

*/

#include<stdio.h>

//1(a)

struct Card{

char* face;

char* suit;

};

//2(a)

void changeSuitToClubs(Card card)

{

card.suit="Clubs";

}

int main()

{

struct Card firstCard;

//1(b)

struct Card secondCard;

firstCard.face="Jack";

//1(c)

secondCard.face="Queen";

firstCard.suit="Hearts";

//1(d)

secondCard.suit="Spades";

//1(e)

printf("%s of %s ",firstCard.face, firstCard.suit);

printf("%s of %s ",secondCard.face, secondCard.suit);

/*

We will print 'face of firstCard with Suit of secondCard and vice-versa

*/

printf("%s of %s ",firstCard.face, secondCard.suit);

printf("%s of %s ",secondCard.face, firstCard.suit);

//2(b)

changeSuitToClubs(firstCard);

printf("%s ",firstCard.suit);

/* NO Suit didn't changed

because 'card' was passed by value, in this case modification in done on local copy

if we pass by reference the modification will be visible in parent() */

printf(" ");

//2(c)

printf("%s ",secondCard.suit);

changeSuitToClubs(secondCard);

printf("%s ",secondCard.suit);

/* NO Suit didn't changed

because 'card' was passed by value, in this case modification in done on local copy

if we pass by reference the modification will be visible in parent() */

}

/*

Output:

Jack of Hearts

Queen of Spades

Jack of Spades

Queen of Hearts

Hearts

Spades

Spades
