{
int *temp=temp1;
temp1=temp2;
temp2=temp;
}
int main()
{
int a=100;
int b=200;
int c=300;
trick(&a,&b;
trick(&a,&c);
cout< }

Answer 1

Answer:

Explanation: we are using in this question call by reference method, where we passes address of that variables (address of a and b) to swapping value between two number

step 1: when we are swapping between a and b then we consider of c as a third variavble then we can swap value of a and b

so here  values will be  a=200 and b=100;

but next after second time calling a function we find

step 2: when we are swapping  between a and  c then we condsider  of b as a third variable  then we can swap value of a and  c

so here value will be  a=300 and c =100

so now values of a , b and c

a=300

b=100

c=100
