Answer:

The following C++ program is displayed below. No output is produced as per the requirements stated in the question.

#include <iostream>

using namespace std;

int main() {    

   // declaration and initialization of integer variables

   int k, memberID = 12, nMembers=5;

   bool isAMember;    

   // declaration and initialization of integer array

   int currentMembers[] = {12, 34, 56, 78, 90};    

   for(k=0; k<nMembers; k++)

   {

       if(memberID == currentMembers[k])

       {

           // if the member is found in the array, the loop exits using the break statement

           isAMember = true;

           break;

       }

       else

           isAMember = false;

   }    

   return 0;

}

Explanation:

The program starts with the declaration and initialization of integer variables, followed by the definition of an array that holds the identifiers of all members.

The Boolean variable is declared, although it isn't initialized at this point.

int k, memberID = 12, nMembers=5;

bool isAMember;

int currentMembers[] = {12, 34, 56, 78, 90};

Subsequently, the array containing the members' IDs is searched for the specific member ID. This action is performed using a for loop along with an if-else condition within that loop.

If the member ID exists in the array, the variable isAMember is set to true; otherwise, it is marked as false.

If isAMember is set to true, the break statement allows for the loop to be exited early.

for(k=0; k<nMembers; k++)

   {

       if(memberID == currentMembers[k])

       {

           isAMember = true;

           break;

       }

       else

           isAMember = false;

 }

The break statement is utilized since any other IDs in the array won't match the given member ID and thus, the variable isAMember would incorrectly be initialized to false even if the member ID is present in the array. Therefore, it's crucial to terminate the loop as soon as the matching member ID is located.

This program can be tested by utilizing different member ID values and varying the size of the array.

Answer:

The code placed where "/*Your solution goes here */" is as follows:

while(numInsects<200) // while loop

       {

            System.out.print(numInsects+" "); // output statement

            numInsects=numInsects*2; // operation to double the value.

       }

Output:

• If the input is 16, the result is 16 32 64 128.
• If the input is 25, the result is 25 50 100.

Explanation:

• The above Java code fills the section designated as "Your solution" and will operate correctly.
• The program accepts a user input and continues to print double the value until it reaches 200 or more.
• The while loop evaluates whether the value remains below 200. If so, the operation proceeds; otherwise, it stops.

Answer:

tryagain = "Y"

while tryagain.upper() == "Y":

    x1 = int(input("x1: "))

    y1 = int(input("y1: "))

    x2 = int(input("x2: "))

    y2 = int(input("y2: "))

    x3 = int(input("x3: "))

    y3 = int(input("y3: "))

    area = abs(x1 *(y2 - y3) + x2 * (y1 - y3) + x3 * (y1 - y2))

    if area > 0:

         print("Inputs form a triangle")

    else:

         print("Inputs do not form a triangle")

    tryagain = input("Press Y/y to try again: ")

Explanation:

To check for this, we will simply compute the area of the triangle given that inputs are on a coordinate plane i.e. (x,y).

An area greater than 0 means it's a triangle

Conversely, if not, it's not a triangle.

This line starts the loop with variable tryagain set to Y

tryagain = "Y"

while tryagain.upper() == "Y":

Following lines retrieve the triangle's coordinates     x1 = int(input("x1: "))

    y1 = int(input("y1: "))

    x2 = int(input("x2: "))

    y2 = int(input("y2: "))

    x3 = int(input("x3: "))

    y3 = int(input("y3: "))

Now, this computes the area

    area = abs(x1 *(y2 - y3) + x2 * (y1 - y3) + x3 * (y1 - y2))

Finally, this checks the condition mentioned above.

    if area > 0:

         print("Inputs form a triangle") This message appears if the condition is true

    else:

         print("Inputs do not form a triangle") This is printed if the condition is not met

    tryagain = input("Press Y/y to try again: ") It prompts the user to input new values

Answer:

Below is the Python code:

stock_prices = input().split() #this takes input and separates it into a list

for price in stock_prices: #this loops through each stock price

   print("$",price) #this outputs each stock price prefixed by a dollar sign

Explanation:

The logic behind the program is clearly outlined in the attached comments. To illustrate the program's workings, let's consider an example:

Imagine the user inputs the stock_prices values of

34.62 76.30 85.05

The input() method captures user input, while the split() method divides the input string, providing a list of strings as:

['34.62', '76.30', '85.05']

Following that, the loop statement for price in stock_prices: iterates through each item in the list, and print("$",price) displays each value from the list on the output screen with a dollar sign, as follows:

$ 34.62                                                                                                            

$ 76.30                                                                                                            

$ 85.05
