What does fun2() do in general?
int fun(int x, int y)
{
if (y == 0) return 0;
return (x + fun(x, y-1));
}
int fun2(int a, int b)
{
if (b == 0) return 1;
return fun(a, fun2(a, b-1));
}
int fun(int x, int y)
{
if (y == 0) return 0;
return (x + fun(x, y-1));
}
int fun2(int a, int b)
{
if (b == 0) return 1;
return fun(a, fun2(a, b-1));
}
- a)x*y
- b)x+x*y
- c)xy
- d)yx
Correct answer is option 'C'. Can you explain this answer?

Explanation:
The given code defines two functions - fun and fun2.
Function fun:
- It takes two integer inputs x and y.
- If y is equal to 0, it returns 0.
- Otherwise, it recursively calls itself with x and y-1 as inputs and returns x multiplied by the result of the recursive call.
Function fun2:
- It takes two integer inputs a and b.
- If b is equal to 0, it returns 1.
- Otherwise, it recursively calls itself with a and b-1 as inputs and passes the result of the recursive call to the function fun with a and the recursive result as inputs. It returns the result of the fun function call.
Now, let's understand what happens when we call the function fun2 with inputs a=2 and b=3:
- fun2(2,3) is called.
- Since b is not equal to 0, it calls itself with a=2 and b-1=2 as inputs.
- fun2(2,2) is called.
- Since b is not equal to 0, it calls itself again with a=2 and b-1=1 as inputs.
- fun2(2,1) is called.
- Since b is not equal to 0, it calls itself again with a=2 and b-1=0 as inputs.
- fun2(2,0) is called.
- Since b is now equal to 0, it returns 1.
- The result of the previous recursive call is passed to the fun function with a=2.
- fun(2,1) is called.
- It calls itself with x=2 and y-1=0 as inputs.
- Since y is now equal to 0, it returns 0.
- The result of the previous fun call is multiplied by x=2 and returned.
- The final result of fun2(2,3) is 2 multiplied by the result of fun(2,2), which is 4.
- Therefore, the correct option is C) xy, which is equivalent to 2*3=6.
In summary:
- Function fun multiplies x by y recursively.
- Function fun2 calls fun recursively and passes the result to the next recursive call.
- When we call fun2(2,3), it returns 2 multiplied by the result of fun(2,2), which is 4.
- Therefore, the answer is C) xy, which is equivalent to 2*3=6.
