Answer 1

> What is the output?
You can fin it ou yourself if your run the code and check the console.

> How does the output come to be like that?
I think it gets clearer when you use the curly brackets on the if-statements:
int i=3;
if(!i) {
i++;
}
i++;
if(i==3) {
i+=2;
}
i+=2;

Answer 2

Curly braces is used for multiline statements.

If there is no curly braces it means only single statement would be there

so

if(!i)
i++;
i++;

is like

if (!i)
i++;

i++;
