CpjJwWHV    int i=5;
int b=++i + ++i + ++i;
printf("%d",b);

for like this the o/p is 21

void main()
{
int i=5;
int b=++i+++i+++i;
printf("%d",b);

}

for this compilation error.

CpjJwWHV   int b=5;
int b=++i + ++i + ++i;
printf("%d",b);

for this o/p --> 22 NOT 21,

int i=5;
int b=++i+++i+++i;
printf("%d",b);
for this compilation error bcoz when scanning is done by compiler,it is confused whether (consider middle i -- > +++i+++)++ i is used or i++ used for increment,at a time compiler can done 1 modification so error

CpjJwWHV   the answer is 24.....there r 3 pre increment....so the value becomes 8 of I.....then it is assigned to all tree position of I....so 8+8+8=24...
