Question

1.)What would be the output of the following programs:

(a)

main( ) {

int i = 5, j = 2 ;

junk ( i, j ) ;

printf ( "\n%d %d", i, j ) ;

}

junk ( int i, int j ) { i = i * i ; j = j * j ; }

(b)

main( ) {

int i = 5, j = 2 ;

junk ( &i, &j ) ;

printf ( "\n%d %d", i, j ) ;

}

junk ( int *i, int *j ) { *i = *i * *i ; *j = *j * *j ;

}

(c)

main( ) {

int i = 4, j = 2 ;

junk ( &i, j ) ;

printf ( "\n%d %d", i, j ) ;

}

junk ( int *i, int j ) { *i = *i * *i ; j = j * j ; }

(d)

main( ) {

float a = 13.5 ;

float *b, *c ; b = &a;

/* suppose address of a is 1006 */ c = b ;

printf ( "\n%u %u %u", &a, b, c ) ;

printf ( "\n%f %f %f %f %f", a, *(&a), *&a, *b, *c ) ;

}

Answer 1

a)

5 2

b)

25 4

c)

16 2

d)

1006 1006 1006
13.500000 13.500000 13.500000 13.500000 13.500000
