Answer:
Following are the code to this question:
import math# import math module
def RaiseToPower(): # defining a function RaiseToPower
r= math.pow(2,1/12) # defining r variable that calcualte the decimal point value.
return r # return r variable value.
f0= float(input()) #defining f0 variable that hold input frequency .
for n in range(0,5):#defining for loop to count all frequency
fn = f * math.pow(RaiseToPower(),n) # defining fn variable that calls method RaiseToPower and multiply the value by frequency
print(fn,end=' ') # use print method to prints all five frequency
Output:
440
440.0 466.1637615180899 493.8833012561241 523.2511306011974 554.3652619537443
Explanation:
Description of the above python code can be defined as follows:
- In the above code first we import the package of the math module for converting frequency, after importing package a "RaiseToPower" method is declared, inside the method r variable is declared, that counts decimal value and return its value.
- In the next step, "f0" a frequency variable is declared that input a value from the user and defined a for loop to in the loop fn variable declared, calls the method and pass its input value and stores its decimal points and at the last print its value.
Answer: True
Explanation: In data mining, they use statistics component for the analyzing of the large amount of data and helps to deal with it. Statistics provide the techniques for the analyzing, evaluating and dealing with the data that is known as data mining.Data statistics provide the help to organize large data in a proper form and then analyze it. Thus, the statement given is true that data mining must use statistics to analyse data.
In the C programming language, you can't determine the array size from the parameter, so you have to pass it in as an extra parameter. The solution could be:
#include <stdio.h>
void swaparrayends(int arr[], int nrElements)
{
int temp = arr[0];
arr[0] = arr[nrElements - 1];
arr[nrElements - 1] = temp;
}
void main()
{
int i;
int myArray[] = { 1,2,3,4,5 };
int nrElements = sizeof(myArray) / sizeof(myArray[0]);
swaparrayends(myArray, nrElements);
for (i = 0; i < nrElements; i++)
{
printf("%d ", myArray[i]);
}
getchar();
}
In higher languages like C# it becomes much simpler:
static void Main(string[] args)
{
int[] myArray = {1, 2, 3, 4, 5};
swaparrayends(myArray);
foreach (var el in myArray)
{
Console.Write(el + " ");
}
Console.ReadLine();
}
static void swaparrayends(int[] arr)
{
int temp = arr[0];
arr[0] = arr.Last();
arr[arr.Length - 1] = temp;
}
