The function declaration that could be used to input data from the keyboard into the array is d. void input(int array[], int &numElements, int MAX_SIZE).
This function declaration takes in an array, a variable to store the number of elements to be input, and a constant to represent the maximum size of the array. The array parameter is passed by reference, allowing the function to directly modify the values stored in the array. The numElements parameter is also passed by reference, allowing the function to update the value of the variable outside the function. Finally, the MAX_SIZE parameter is a constant that is used to ensure that the function does not attempt to input more elements than the size of the array.
To input data from the keyboard into the array, the function would use a loop to prompt the user to input values for each element of the array. The loop would continue until the number of elements input equals the value stored in the numElements parameter or until the maximum size of the array is reached. Within the loop, the function would use the standard input function, such as scanf() in C, to read values from the keyboard and store them in the array.
Overall, the function declaration d. void input(int array[], int &numElements, int MAX_SIZE) is a suitable choice for inputting data from the keyboard into an array, as it allows for efficient modification of the array and tracking of the number of elements input.

Write code to complete raise to power(). note: this example is for practicing recursion; a non-recursive function, or using the built-in function math.pow(), would be more common.
Code:
def power(base, exponent):
if exponent == 0:
return 1
else:
return base * power(base, exponent - 1)
This function uses recursion to raise a given base to the power of a given exponent. The base case is when the exponent is equal to zero, in which case the function returns 1. Otherwise, the function multiplies the base by the result of calling the power function Code recursively with the base and exponent reduced by 1. This continues until the base case is reached, at which point the final result is returned. Recursion allows the function to simplify the problem by reducing it to smaller subproblems, which are then solved recursively until the base case is reached.

To use pointers for heap management, a programming language must provide a mechanism for dynamically allocating and deallocating memory on the heap, such as the "malloc" and "free" functions in C and C++.
If a programming language wants to use pointers for heap management, it must provide a mechanism for dynamically allocating and deallocating memory on the heap.
Heap memory is a region of memory that is not managed by the program stack and can be allocated and deallocated dynamically during program execution.
Heap memory is typically used to store data structures that have a variable size or lifetime, such as arrays, linked lists, and objects.
To allocate memory on the heap, a programming language must provide a mechanism for requesting a block of memory of a specified size from the operating system.
In languages like C and C++, this is typically done using the "malloc" function, which returns a pointer to a block of memory of the requested size.
The programmer can then use this pointer to access and manipulate the allocated memory.
Similarly, to deallocate memory on the heap, the programming language must provide a mechanism for returning the memory block to the operating system.
In C and C++, this is typically done using the "free" function, which takes a pointer to the block of memory to be deallocated.
Other programming languages may provide different mechanisms for heap management, such as garbage collection or automatic memory management, which handle memory allocation and deallocation automatically without the need for explicit pointer manipulation.

The sub-domain is an optional part that usually comes before the main domain name (e.g., "www" or "blog"). The domain name is the primary identifier of the website (e.g., "brainly"), and the top-level domain name (TLD) is the extension at the end of the domain name (e.g., ".com", ".edu", ".gov", or ".net"). We use these components in combination to locate websites on the internet.

Using C++
The program in the Programming Example: Fibonacci Number does not check:
Whether the first number entered by the user is less than or equal to the second number and whether both the numbers are nonnegative.
Whether the user entered a valid value for the position of the desired number in the Fibonacci sequence.
Rewrite that program so that it checks for these things.
NOTES:
If an invalid number is entered for case 1 above, prompt the user to enter both numbers again.
If an invalid number is entered for case 2, prompt the user to enter a value until a valid value is entered.
Here is what I got so far, I am struggling with the last part (handling invalid numbers)
#include
using namespace std;
int main()
{
int previous1;
int previous2;
int current;
int counter;
int nthFibonacci;
cout<<"Enter First two number of fiboncci";
cin>>previous1>>previous2;
cout<
if(previous1>previous2)//to check whether first number is less than or equal to second
{
cout<<"Invalid sequence to start with exiting the program"<
return 0;
}
if(previous1<0 || previous2<0)//to check both are positive
{
cout<<"sequence contains negeative number exiting ...."<
return 0;
}
cout<<"Enter the position of desired Fibonacci Number : ";
cin>>nthFibonacci;
if(nthFibonacci<=0)//to check validity of position
{
cout<<"invalid position exiting..."<
return 0;
}
cout<
if(nthFibonacci==1)
current=previous1;
else if(nthFibonacci==2)
current=previous2;
else
{
counter =3;
while(counter<=nthFibonacci)
{
current=previous2+previous1;
previous1=previous2;
previous2=current;
counter++;
}
}
cout<<"The Fibonacci number at position "<
Here is the modified program in C++ that checks for the given conditions:
#include
using namespace std;
int main()
{
int previous1, previous2, current, counter, nthFibonacci;
//taking input for first two numbers of Fibonacci sequence
cout<<"Enter the first two numbers of Fibonacci sequence: ";
cin>>previous1>>previous2;
//checking for invalid sequence
while(previous1>=previous2 || previous1<0 || previous2<0)
{
cout<<"Invalid sequence! Please enter both numbers again: ";
cin>>previous1>>previous2;
}
//taking input for position of desired Fibonacci number
cout<<"Enter the position of desired Fibonacci number: ";
cin>>nthFibonacci;
//checking for invalid position
while(nthFibonacci<=0)
{
cout<<"Invalid position! Please enter a valid position: ";
cin>>nthFibonacci;
}
//calculating the nth Fibonacci number
if(nthFibonacci==1)
current=previous1;
else if(nthFibonacci==2)
current=previous2;
else
{
counter = 3;
while(counter<=nthFibonacci)
{
current = previous2 + previous1;
previous1 = previous2;
previous2 = current;
counter++;
}
}
//displaying the result
cout<<"The Fibonacci number at position "<
