Answer:
vec[0].push_back(10)
Explanation:
Given
Declaration: vector <int> vec
Required
Assign 10 to the first element
This can be done using the push_back keyword.
The syntax is: vectorname[position].push_back(value);
In this case:
vectorname = vec
position = 0 i.e. first element
value = 10
So, we have:
vec[0].push_back(10)

Program Explanation:
Defining the header file.Defining a class "Car", inside the three variables "carName, ignition, and currentSpeed" is declared that are "string, bool, and integer" types.Inside the class, "default and parameterized constructor" and get and set method has defined that set and returns the parameter values.Outside the class, another class "Convertible" (child) is declared that inherit the base class "Car".Inside the child class, "default and parameterized constructor" is defined, which inherits the base class constructor.In the child class parameterized constructor it takes four parameters, in which 3 are inherited from the base class and one is bool type that is "t".In this class, a method "setTop" is defined that sets the "t" variable value and defines a show method that prints the variable values.Outside the class, the Main method is defined that creating the child class object and calling the parameterized constructor and other methods to print its values.Program:

what presents information about the document, the progress of
current tasks and the status of certain commands and keys?
Answer: status bar
Explanation:
The status bar refers to the horizontal window that's found at the bottom of the parent window whereby an application will show different kinds of status information.
The main function of the status bar is to simply display information withnragrds to the current state of the window. Therefore, the status bar helps in the presentation of information about the document, indicates progress of
current tasks and also the status of some commands and keys.

Create a new Java project/class called ChangeUp. Create an empty int array of size 6. Create a method called populateArray that will pass an array, use random class to choose a random index and prompt the user to enter a value, store the value in the array. Note: Generate 6 random index numbers in an attempt to fill the array. Create a method called printArray that prints the contents of the array using the for each enhanced loop. Submit code. Note: It is possible that your array won't be filled and some values will still have 0 stored. That is acceptable.

Explanation:
In the code provided, we are creating an array of size 6 to store integer values. The objective is to populate this array by taking input from the user for specific indexes chosen randomly.
To achieve this, we have defined two methods: populateArray and printArray.
The populateArray method takes an array as a parameter and fills it with values provided by the user. Here's how it works:
We create an instance of the Random class to generate random numbers and a Scanner object to read user input.We also create a boolean array called filledIndexes of the same size as the main array. This array will keep track of the indexes that have already been filled.Next, we use a loop to iterate six times (since we want to fill six elements in the array).Inside the loop, we generate a random index using random.nextInt(6). However, we want to make sure that we don't fill the same index twice. So, we check if the index is already filled by checking the corresponding value in the filledIndexes array.If the index is already filled (i.e., filledIndexes[index] is true), we generate a new random index until we find an unfilled one.Once we have a valid, unfilled index, we mark it as filled by setting filledIndexes[index] to true.We then prompt the user to enter a value for the chosen index and read the input using scanner.nextInt(). We store this value in the main array at the corresponding index.This process is repeated six times, ensuring that each index is filled with a unique value.The printArray method is responsible for printing the contents of the array. It uses a for-each enhanced loop to iterate over each element in the array and prints its value.
**By separating the population and printing logic into separate methods, the code becomes more modular and easier to understand.**

Explanation:
Create a program that will compute the voltage drop across each resistor in a series circuit consisting of three resistors. The user is to input the value of each resistor and the applied circuit voltage. The mathematical relationships are 1. Rt- R1 R2 + R3 It Vs/Rt Where Rt -Total circuit resistance in ohms R1,R2,R3 Value of each resistor in ohms It - Total circuit current in amps Vs -Applied circuit voltage Vn- Voltage drop across an individual resistor n (n-1, 2 or 3) in volts Rn-R1,R2, or R3
Use the values of 5000 for R1, 3000 for R2,2000 for R3, and 12 for Vs. The output of the program should be an appropriate title which identifies the program and include your name. All values should be accompanied by appropriate messages identifying each. Submit a printout of your program and the printed output to your instructor
Answer:
The program in Python is as follows:
R1 = int(input("R1: "))
R2 = int(input("R2: "))
R3 = int(input("R3: "))
Rt = R1 + R2 + R3
Vs = int(input("Circuit Voltage: "))
It = Vs/Rt
V1= It * R1
V2= It * R2
V3= It * R3
print("The voltage drop across R1 is: ",V1)
print("The voltage drop across R2 is: ",V2)
print("The voltage drop across R3 is: ",V3)
Explanation:
The next three lines get the value of each resistor
R1 = int(input("R1: "))
R2 = int(input("R2: "))
R3 = int(input("R3: "))
This calculates the total resistance
Rt = R1 + R2 + R3
This prompts the user for Circuit voltage
Vs = int(input("Circuit Voltage: "))
This calculates the total circuit voltage
It = Vs/Rt
The next three line calculate the voltage drop for each resistor
V1= It * R1
V2= It * R2
V3= It * R3
The next three line print the voltage drop for each resistor
print("The voltage drop across R1 is: ",V1)
print("The voltage drop across R2 is: ",V2)
print("The voltage drop across R3 is: ",V3)
different the need for external or secondary memory
Answer:
Secondary storage is needed to keep programs and data long term. Secondary storage is non-volatile , long-term storage. Without secondary storage all programs and data would be lost the moment the computer is switched off.
External storage enables users to store data separately from a computer's main or primary storage and memory at a relatively low cost. It increases storage capacity without having to open up a system.
