On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance
lesantik [10]

Answer:

In C:

#include <stdio.h>

#include <math.h>

int main(){

   float f0,r,temp;

   r = pow(2.0,1.0/12);

   printf("f0: ");    scanf("%f", &f0);

   temp = f0;

   for(int i = 0; i<=4;i++){

       f0 = f0 * pow(r,i);

       printf("%.2lf ", f0);

       f0 = temp;    }

   return 0;

}

Explanation:

This declares f0, r and temp as float

   float f0,r,temp;

This initializes r to 2^(1/12)

   r = pow(2.0,1.0/12);

This prompts the user for f0

   printf("f0: ");    scanf("%f", &f0);

This saves f0 in temp

   temp = f0;

This iterates the number of keys from 0 to 4

   for(int i = 0; i<=4;i++){

This calculates each key

       f0 = f0 * pow(r,i);

This prints the key

       printf("%.2lf ", f0);

This gets the initial value of f0

       f0 = temp;    }

   return 0;

natta225 [31]

Answer:

1. E

2. C

3. F

4. D

5. A

6. B

Explanation:

CPU: this is known as the central processing unit and it is considered to be the brain of a computer system. It is the system unit where all of the processing and logical control of a computer system takes place.

A. Decode unit: decodes instructions and data and transmits the data to other areas in an understandable format.

B. Register unit: contains many separate, smaller storage units. Modern CPUs need only a few nanoseconds to execute an instruction when all operands are in its registers.

C. Bus unit: it is used to connect all the other major components together, accepts data, and sends data through the input and output bus sections.

D. Control unit: control of the overall operations of the CPU. The component of the central processing unit (CPU) that controls the overall operation of a computer is the control unit. It comprises of circuitry that makes use of electrical signals to direct the operations of all parts of the computer system. Also, it instructs the input and output device (I/O devices) and the arithmetic logic unit how to respond to informations sent to the processor.

E. Arithmetic logic unit (ALU): performs mathematical functions on data stored in the register area.

F. Cache: small temporary memory area that separates and stores income data and instructions.

Write a program that reads a string consisting of a positive integer or a positive decimal number and converts the number to the
jeka94

Answer:

#include <iostream>

#include <string>

#include <stack>

#include <math.h>

using namespace std;

int main() {

  string s;

  double n=0;

  int position=0;  

  stack<int> wholeNumbers;

  cout<<"Enter a decimal number:";

  cin>>s;

  string::iterator counter = s.begin();

  while(*counter!='.' && counter!=s.end()){

      wholeNumbers.push(*counter-48);

      counter++;

      position=position+1;

     

  }

  for(int i=0;i<position;i++){

      n=n+(wholeNumbers.top()*pow(10,i));

      wholeNumbers.pop();

  }

  position=-1;

  if(counter!=s.end()){

      counter++;

  }

  while(counter!=s.end()){

      n=n+((*counter-48)*pow(10,position));

      position=position-1;

      counter++;      

  }

  cout<<n;

}

Explanation:

  • Inside the while loop, push the push a number to the wholeNumbers stack by subtracting it with 48.
  • Increment the counter and position variable by 1 inside the while loop.
  • Count the number of digit, push each digit to top of stack and find the end of the number,
  • Run a for loop up to the value of position variable and pop a value from the wholeNumbers stack.
