Answer:
The code to this question can be given as:
Code:
int lastVector = newScores.size() -1; //define variable lastVector that holds updated size of newScores.
newScores = oldScores; //holds value.
for (i = 0; i < SCORES_SIZE - 1; i++) //define loop.
{
newScores.at(i) = newScores.at(i+1); //holds value in newScores.
}
newScores.at(lastVector) = oldScores.at(0); //moving first element in last.
Explanation:
- In the given C++ program there are two vector array is defined that are "oldScores and newScores". The oldScores array holds elements that are "10, 20, 30, 40".
- In the above code, we remove the array element at first position and add it to the last position. To this process, an integer variable "lastVector" is defined.
- This variable holds the size of the newScores variable and uses and assigns all vector array elements from oldScores to newScores. In the loop, we use the at function the removes element form first position and add in the last position.
- Then we use another for loop for print newScores array elements.

Answer:
Following are the code in Java Language:
Scanner sc = new Scanner(System.in); // create a instance of scanner class
DecimalFormat frmt = new DecimalFormat("0.###"); // create a instance of // DecimalFormat class
System.out.println ("Enter the value: ");
double number = scan.nextDouble(); // Read the value by thje user
System.out.println (fmmt.format(Math.pow(number, 4))); // display the value
Explanation:
Following are the description of the code
- Create an instance scanner class i.e "sc".
- Create an instance of DecimalFormat class i.e "frmt".
- Read the value by the user in the "number" variable of type double by using the nextDouble()method.
- Finally, display the value by using System.out.println method. In this, we call the method format. The Math.pow() function is used to calculating the power up to the fourth value.
