Other comment is related to the expression..
But if u see, in case of printf(++j,j++,j) then u have to start from Right to left : j=1 (not stored in stack , waiting for the updated value), j++ = 1 (used).. j becomes 2 and then ++j = 3 .. LAst updated value is 3..

So the output is 3,1,3

Cheers..

It is updating… But it will update the values only at the end of the expression..

for eg. : if u use : printf(p++ + p++) nd if p = 5
Then result will be 10.
But in next statement print the value of p . It would have become 7. It is updating but at the end of the expression.

Thanks

printf maintains a stack of values to be printed. It does not print each value separately, first it will complete it’s stack than starts printing.

In case of ++j and j printf will store the last updated value in the stack. and for j++ it stores the current value in the stack and then increments it.

now u will be able to solve this.
