Well, you need to partition your hard drive. Partitioning your hard drive designates usable space on your hdd.
And you need to format your hard drive. Formatting installs a file system on to your hard drive, it allows the operating system to read, write and overall understand the data stored on the disk. Without it, an OS cannot keep track of file locations, nor can it typically identify already used sectors (space) on a hdd.
However, neither of these two concepts are tests.
Answer:
import java.util.Arrays;
import java.util.Scanner;
public class num1 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter length of the array:");
int len = in.nextInt();
double [] temps = new double[len];
double avgTem;
int k =0;
double total = 0;
for( k=0; k<temps.length; k++){
System.out.println("Enter values for the array");
temps[k]=in.nextDouble();
}
System.out.println("The Arrays contains the following values");
System.out.println(Arrays.toString(temps));
// Computing the average of the values
for(k=0; k<temps.length; k++){
total = total+temps[k];
}
avgTem = total/(temps.length);
System.out.println("The average Temperature is: "+avgTem);
}
}
Explanation:
- Using Java programming language
- Import the Scanner class to receive user input
- Prompt User for the length of the Array, receive and store in a variable len;
- Declare a new double array of size len double [] temps = new double[len];
- Using a for loop, continually prompt user to enter values into the array
- Display the values of the array using Java's Arrays.toString method
- Use another for loop to add up all the elements in the arraay and store in the variable called total
- Outside the second for loop calculate the average avgTem = total/(temps.length);
- Display the average temp.
Answer: Quality is the parameter which describes about the distinctive trait presented by something.The measurement of the quality is based on whether or not the substance is able to fulfill the requirement of the client.
In respect with the computing field ,quality is the characteristic that is supposed to be good if there is presence of no defects or damage and is able to meet the requirement of the user or client. This parameter can be for devices, programming languages, software etc.
Answer:
- import statistics
- def st_dev(file_name):
- with open(file_name) as file:
- data = file.readlines()
- numList = []
- for x in data:
- numList.append(int(x))
-
- return statistics.pstdev(numList)
- print(st_dev("text1.txt"))
Explanation:
The solution code is written using Python.
To ease the calculation task, we can import Python statistics module to use the pstdev method to calculate the population standard deviation of a list of numbers (Line 1).
Next, create a st_dev function that take single argument file_name (Line 3). In the function, it will open the input file and read the data line by line (Line 4-5). Create a for loop to traverse through each line of the data which is an integer and append it to numList (Line 7-8). We can pass the numList to pstdev method (Line 10) and return the resulting standard deviation value as output.
We test the function by passing a file which hold a list of integer values in each line (Line 12).
