Arada [10]

Answer:

An analog player changes the recording to digital, and sends the digital signal to a speaker to be played.

Explanation:

An audio signal can be defined as a representation of sound, either as an analog or digital signals.

An analog audio signal refers to a continuous signal that is represented by a changing level of quantity such as voltage with respect to time and sequence of bits such as 16kbps, 32kbps, 64kbps, 96kbps, 128kbps, 196kbps, and 320kbps.

Note: Kbps means kilobits per seconds.

On the other hand, a digital audio signal can be defined as the recording, storage and reproduction of sounds by encoding the audio signals in a digitized format.

An analog player is a type of audio player such as a turntable, which is designed to read informations as a continuous signal.

In order to play a digital audio or music files, an analog player changes the recording to a digital format and sends the digital signal to a speaker to be played.

A speaker can be defined as an electronic output device that is typically used for the conversion of an electromagnetic wave to sound wave.

Basically, this conversion is done through the help of a hardware electronic component known as transducers.

Andrej [43]

Answer:

#include <iostream>

#include <cstring>

using namespace std;

void replacePeriod(char* phrase) {

int i = 0;

while(*(phrase + i) != '\0')

{

if(*(phrase + i) == '.')

*(phrase + i) = '!';

i++;

}

int main() {

const int STRING_SIZE = 50;

char sentence[STRING_SIZE];

strcpy(sentence, "Hello. I'm Miley. Nice to meet you.");

replacePeriod(sentence);

cout << "Updated sentence: " << endl;

cout << sentence << endl;

return 0;

}

Explanation:

Create a function called replacePeriod that takes a pointer of type char as a parameter.
Loop through the end of phrase, check if phrase has a period and then replace it with a sign of exclamation.
Inside the main function, define the sentence and pass it as an argument to the replacePeriod function.
Finally display the updated sentence.
