file stream objects connect a program to a . group of answer choices a. keyboard b. terminal screen c. storage device d. file

Answers

Answer 1

File stream objects are a very important tool in programming, as they allow a program to connect to a storage device, such as a file. This means that the program can read and write data to and from the file, allowing it to store information and retrieve it at a later time.

option C is the correct answer

In C++, file stream objects are created using the fstream library, which provides a set of classes and functions that allow you to work with files. These classes include ifstream (input file stream), ofstream (output file stream), and fstream (both input and output file stream). When a file stream object is created, it is associated with a specific file on the computer's storage device. This means that any data that is read from or written to the stream will be stored in that file. In order to open a file stream object, you must specify the name of the file and the mode in which it should be opened (such as "read-only" or "write-only"). Once the file stream object is open, you can use a variety of functions to read and write data to and from the file. For example, you can use the getline function to read a line of text from the file, or the << operator to write data to the file. File stream objects are a crucial part of programming, as they allow programs to store and retrieve data in a persistent way. By connecting to a storage device like a file, they give programs the ability to work with data even when the program is not running, making them a powerful tool for data storage and management.

option C is the correct answer

Answers

To write a script that reads the current time and converts it to a time of day in hours, minutes, and seconds, plus the number of days since the epoch, follow these steps:

1. Import the time module
2. Get the current time in seconds since the epoch
3. Calculate the number of days since the epoch
4. Calculate the remaining seconds
5. Convert the remaining seconds to hours, minutes, and seconds

Here's the script:

```python
import time

# Get the current time in seconds since the epoch
current_time = time.time()

# Calculate the number of days since the epoch
days_since_epoch = int(current_time // 86400)

# Calculate the remaining seconds
remaining_seconds = current_time % 86400

# Convert the remaining seconds to hours, minutes, and seconds
hours = int(remaining_seconds // 3600)
remaining_seconds %= 3600
minutes = int(remaining_seconds // 60)
seconds = int(remaining_seconds % 60)

# Print the result
print(f"Time: {hours:02d}:{minutes:02d}:{seconds:02d}, Days since epoch: {days_since_epoch}")
```

When you run this script, it will display the current time in hours, minutes, and seconds, along with the number of days since the epoch (1 January 1970).

What is CIA?

The Central Intelligence Agency (CIA) is the main foreign intelligence and counterintelligence organization of the United States government. The Office of Strategic Services (OSS) from World War II gave rise to the Central Intelligence Agency (CIA), which was officially founded in 1947.

Duplication, competition, and a lack of coordination plagued earlier U.S. intelligence and counterintelligence efforts, which were carried out by the military and the Federal Bureau of Investigation (FBI). These issues persisted, in part, into the twenty-first century.

The establishment of a civilian intelligence agency by the United States, the last of the major powers, was charged with gathering top-secret data for decision-makers.

Answers

Answer:

The torque is 15 N·m

Explanation:

The given parameters are;

The length of the torque wrench = 0.5 m

The force applied on the torque wrench = 30 N

The torque at the end of the torque wrench is equal to the applied force multiplied by the perpendicular distance from the point of application of the force to the end of the torque wrench

Therefore;

Torque = The force applied on the torque wrench handle × The length of the torque wrench

Torque = 30 N × 0.5 m = 15 N·m

Torque = 15 N·m.

Causal validity is the extent to which we can confidently make causal claims about the variables in an experiment. It refers to whether we can conclude that changes in one variable directly cause changes in another variable. To establish causal validity, several criteria need to be met.

Answers

Answer:

an interest group

Explanation:

When designing a video game I believe that the best target group would be an interest group. Focusing on a specific interest group will allow you to design a game, knowing that there are people truly passionate about that interest and who will play the game. Targeting an age group makes things difficult because you have to limit your creativity to that age group and even still there may not be much interest in that age group for your category of game. Therefore, an interest group is the best option and gives you the freedom to unlock your creativity without having to limit your game due to age concerns.

the code within a finally block executes when the try block . a. identifies an exception that is not caught b. does not identify any exceptions c. identifies an exception or not, whether or not any exceptions are caught d. identifies one or more exceptions

Answers

The code within a finally block executes when the try block identifies an exception or not, whether or not any exceptions are caught. (Option C)

When we say that the try block "identifies an exception," it means that an exceptional event or error condition has occurred within the try block's code. This could be an error like dividing by zero, accessing an invalid memory address, or encountering a network failure. When such an exception is identified, it interrupts the normal flow of the program and triggers an exception-handling mechanism. In programming languages like Java or Python, the try block is used to enclose the code that may potentially throw an exception. By identifying an exception, we mean that the code within the try block encounters an exceptional situation that requires special handling. This could involve catching the exception, logging an error message, or performing specific actions to handle the exceptional condition.

The option that  does not violate the referential integrity of a database is option D: deleting a row in a foreign key table without deleting the related row in the related primary key table.

What does referential integrity prevent?

You can avoid adding information to table Y that cannot be connected to information in table X by using a referential integrity rule. Referential integrity also requires that any records that are connected to a deleted record from table X be destroyed as well.

When all values for all foreign keys are valid, a database is said to be in referential integrity. A column or combination of columns in a table that must have values that match at least one of the main key or unique key values of a row in its parent table are known as foreign keys.

Note that removing a row from a table with foreign keys without removing the relevant entry from the related primary key table. Referential integrity, however, is broken when a record from the primary key table is deleted.
