Here is a somewhat cryptic solution that works:

#include <algorithm>

#include <cstdlib>

using namespace std;

void q(char c, int count)

{

for (int i = 0; i < count; i++) {

putchar(c);

}

void p(int b1, int plusses)

{

q(' ', b1);

q('+', plusses);

}

int main()

{

for (int i = -3; i <= 3; i++)

{

int pl = min(6, (3 - abs(i)) * 2 + 1);

p(6-pl, pl);

i == 0 ? p(0, 6) : p(6, 0);

p(0, pl);

putchar('\n');

}

getchar();

}

Write C++ code to open a document with the name Hello.txt, place the message "Hello, World!" in the document, and exit the docum

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.
