Answer / manishsoni
# define prod(a,b) a*b
main()
{
int n=2,sum=1; //here given n=2 so
switch(n) //switch(2)
{
case 2: //encounter this case 2;
sum=sum+2; //add sum=1+2;sum=3
case 3: //here no break statement so case
// 3 is checked by this and
// remained that sum=3;
sum*=2; //so sum =3*2;sum=6
break; //here switch is break and sum=6;
default: //default is don't check ;
sum=0;
}
printf("%d",sum); //so print sum=6;
getch();
