What is the return value of f(p,p) if the value of p is initialized to 5 before the call? Note
that the first parameter is passed by reference, whereas the second parameter is passed by
value.
int f (int &x, int c) {
c= c- 1;
if (c= 0) return 1;
x = x+ 1;
return f (x,c )* x;
}
that the first parameter is passed by reference, whereas the second parameter is passed by
value.
int f (int &x, int c) {
c= c- 1;
if (c= 0) return 1;
x = x+ 1;
return f (x,c )* x;
}
- a)3024
- b)6561

What is the return value of f(p,p) if the value of p is initialized to...
&x, int y) {
x = x + y;
y = y + 1;
return x + y;
}
If p is initialized to 5 before the call, then the value of p will be passed by reference to the function. This means that any changes made to p within the function will also affect the value of p outside the function.
When f(p,p) is called, the value of p is 5 and is passed by reference as the first parameter. The second parameter is also initialized to 5.
Within the function, x is a reference to the same memory location as p, so x is also equal to 5. The first line of the function adds y (which is also 5) to x, so now x (and p) is equal to 10.
Then, y is incremented by 1, so y is now equal to 6.
Finally, the function returns the sum of x and y, which is 16 (10+6).
So the return value of f(p,p) if p is initialized to 5 before the call is 16.
x = x + y;
y = y + 1;
return x + y;
}
