Chapter 1: [F] What would be the output of the following programs:

(a)

main( )

{

int   i = 2, j = 3, k, l ;

float   a, b ;

k = i / j * j ;

l = j / i * i ;

a = i / j * j ;

b = j / i * i ;

printf( "%d %d %f %f", k, l, a, b ) ;

}

Output

0 2 0.000000 2.000000

(b)
 
main( )

{

int  a, b ;

a = -3 - - 3 ;

b = -3 - - ( - 3 ) ;

printf ( "a = %d b = %d", a, b ) ;

}

Output

a = 0 b = -6

(c)

main( )

{

float a = 5,  b = 2 ;

int c ;

c = a % b ;

printf ( "%d", c ) ;

}

Output

modulus operator can not be used between floats.

Compiler will give the error and there will be no output.

(d)

main( )

{

printf ( "nn \n\n nn\n" ) ;

printf ( "nn /n/n nn/n" ) ;

}

Output

nn

 nn

nn /n/n nn/n

(e) 

main( ) 

{ 

int a, b ; 

printf ( "Enter values of a and b" ) ; 

scanf ( " %d %d ", &a, &b ) ; 

printf ( "a = %d b = %d", a, b ) ; 

} 

 

Output

Enter values of a and b

1

2

a = 1 b = 2 

(f) 

main( ) 

{ 

int p, q ; 

printf ( "Enter values of p and q" ) ; 

scanf ( " %d %d ", &p, &q ) ; 

printf ( "p = %d q =%d", p, q ) ; 

} 

Output

Enter values of p and q

5 10

p=5 q=10
