gavmur [86]

Answer:

#include<iostream>

#include<fstream>

using namespace std;

int main()

{

ofstream out;

out.open("Hello.txt");

out << "Hello, World!"<< endl;

out.close();

ifstream in;

in.open("Hello.txt");

while(in.good()){

string line;

in >> line;

cout << line << endl;

}

in.close();

return 0;

}

Explanation:

Step 1:

Add all your preprocessor files directive, #include is known as the preprocessor is used to load files needed to run the code.

#include<iostream>: it provides basic input and output services for C++ programs.

#include<fstream>:used to open a file for writing and reading

using namespace std; means you'll be using namespace std means that you are going to use classes or functions (if any) from "std" namespace

Step 2:

ofstream out; his is used to create files and write data to the file

out.open("Hello.txt"); a new file "HELLO.txt" has been created

out << "Hello, World!"<< endl; "Hello World!" has now been writen to the file

out.close(); The file is now closed

This second step opens a new file and writes hello world to the file then closes it.

Step 3:

ifstream in; ifstream in c++ is a stream class which stands for input file stream a is used for reading data from file.

in.open("Hello.txt"); Reopens the file without recreating it. This is a very important step because if not done properly, you might discard the file you previously created and recreate it.

while(in.good()){

in.good() is true if the previous read operation succeeded without EOF being encountered

string line; It declares a string variable line

in >> line; reads the data into the line variable

cout << line << endl; Prints out the line

reopens the file and read the message into a string variable "line". prints out line then exits out of the file.

¿Cuántos megabytes (MB) de capacidad tiene una memoria USB de 16 GB? el que me diga por que le doy una coronita

-Dominant- [34]

Answer:

16,384MB

Explanation:

1GB contiene 1024MB de capacidad. Si multiplicamos esto por 16 veemos que 16GB es igual a 16,384MB. Este seria el espacio exacto, aunque se dice que 1GB tiene 1000MB. Eso es por que la palabra Giga significa x1000 y el numero binario entero mas cercano a 1000 es 1024. Entonces los ingenieros usan este numero para representar la cantidad de espacio en un GB que tambien seria $2^{10}$
