Answer:

The answer to the given question can be given as:

The value of *iptr is 7. and the value of iptr is dynamic.

Explanation:

In the c++ code, it is defined that x is an integer variable that assigns a value which is 7. Then we define a pointer variable that is *iptr. This variable holds an address of the x variable. When we print the value of the iptr variable. if we use the expression *iptr to print value of the pointer variable by cout that is used in c++ for pint values. so the value of the iptr is 7. If we use the expression iptr sent to cout so we show the address of the variable x. In the pointer, it manages the addresses of dynamically allocated so the address of the variable is changed on execution time.

{

   try{

    // declare variable

         double caffeine;

    // scanner object to read input from user

       Scanner scr=new Scanner(System.in);

       System.out.print("Enter the initial amount of caffeine:");

        // read the initial amount of caffeine

           caffeine=scr.nextDouble();

          // calculate amount of caffeine after 6,12,18 hours

          for(int i=1;i<=3;i++)

          {

               System.out.println("After "+ i*6+" hours:"+(caffeine/2)+" mg");

               // update the caffeine after every 6 hours

               caffeine=caffeine/2;

          }

                 

   }catch(Exception ex){

       return;}

}

}

Explanation:

Create a variable "caffeine" to store the initial amount of caffeine given by user. Run a loop for three time, it will calculate the amount of caffeine left after every 6 hours.First it will give the amount of caffeine left after 6 hours, then caffeine left after 12 hours and in last caffeine after 18 hours.

Output:

Enter the initial amount of caffeine:100

After6 hours:50.0 mg

After12 hours:25.0 mg

After18 hours:12.5 mg

The first and second numbers in the Fibonacci sequence are both 1. After that, each subsequent number is the sum of the two prec
vlabodo [156]

Answer:

In Python:

def fib(nterms):

   n1, n2 = 1, 1

   count = 0

   while count < nterms:

       term = n1

       nth = n1 + n2

       n1 = n2

       n2 = nth

       count += 1

   return term

Explanation:

This line defines the function

def fib(nterms):

This line initializes the first and second terms to 1

   n1, n2 = 1, 1

This line initializes the Fibonacci count to 0

   count = 0

The following while loops gets the number at the position of nterms

<em>   while count < nterms: </em>

<em>        term = n1 </em>

<em>        nth = n1 + n2 </em>

<em>        n1 = n2 </em>

<em>        n2 = nth </em>

<em>        count += 1 </em>

This returns the Fibonnaci term

   return term
