why output is 1,1 ?

[Amisha Shah]

programm :

class Cc{

static int f1(int i) {

System.out.print(i + ",");

return 0;

}

public static void main (String[] args) {

int i = 0;

i = i++ + f1(i);

System.out.print(i);

}}

according to me output of this programm is 1,0 . but output is 1,1. how this programm works ?

when you call;

i = i++ +f(i)

you're effectively doing;

i = 0++ + f(1)
=> i = 1 + 0;
=> i = 1;

f(1 ) => outputs "1,"

and the print statement prints the value of i which, is 1

output 1,1

When I run the code, the output is 1,0

doh. my fault.

i = 0++ + f(1)
=> i = 1 + 0;
=> i = 1;


is wrong. It should have read;

i = 0++ + f(1)
=> i = 0 + 0;
=> i = 0;


sorry sorry sorry

you are right.

i = 0++ + f(1)
=> i = 0 + 0;
=> i = 0;

output is 1,0

thanks.
