int b;
void meth(int i,int j)
{
i*=2;
j/=2;
}
}
class output

}

Answer 1

Answer:

The output will be 30

First add than increase

in second also

Answer 2

The output of the given program will be :

10 20

• No changes will be reflected on the value of a and b.

• This is because the variables a & b are passed by value.

• Copy of their values is made on formal parameters of the method meth() i.e. i & j.

• is made on formal parameters of the method meth() i.e. i & j. Therefore changes done on variables i & j are not reflected back on the original arguments.

• the original arguments. Thus the values of a & b remain 10 & 20 respectively and do not change.
