Subject: Computer Applications STD: X ICSE Practice Paper for the Board Examination March 2018 I. Represent the following Mathematical expressions as Java expressions:(1) 4 x (y) (2) 2x2 +3 x (x+y) (3) |x| + a2 + b 2 (4) S 30 + 30 (5) 0.05a3 +b2 (a+b) II. Evaluate the following and write the output:(1) int a=5, b=6, c=2; System.out.println (a+b%c-a*b); System.out.println (c/a + c%a); (2) int x=-4, y=-2; x*=x++ + y++ - ++x; System.out.println ("x= "+x+ "\n y= "+y); (3) char x= 'B '; int y=5; System.out.println (x++%y++ + ++x); System.out.println (x+","+y); (4) int m=100, n=150, k=200; System.out.println ("Output is "+(m%10==n%10)); System.out.println ("Output is "+!(k>m || K%m==0)); (5) int a=20, b=18; char c='a', c1='b'; System.out.println System.out.println System.out.println System.out.println System.out.println System.out.println System.out.println a=b=++a; System.out.println ("Examination "+a+b); ("Output is "+a+c); ("Output is "+(a+c)); (a+c+" is the output"); (c++); (c + b++); (c+" "+b); (a+" "+b); (6) int x=1000, y=500; if(x+y%3==0) System.out.println (x+=y); else System.out.println (x-=y); (7) Write the Output: if (i) char op='a' (ii) char op='d'; switch (op) { case 'a': System.out.println ("case a executed"); case 'b': System.out.println ("case b also executed due to absence of break in case a"); break; case 'c': System.out.println ("case c executed"); default: System.out.println ("User s Input is not matching"); } 1
