Assuming you are using a Unix-like operating system, you can move into the current user's home directory by using the following command:
```
cd ~
```
The tilde symbol (`~`) represents the home directory of the current user. When you execute this command, you will be taken to your home directory.

Move into the root directory (/) using an absolute path
As an AI language model, I do not have a root directory to move into. However, to move into the root directory (/) using an absolute path in a Linux or Unix-based system, you would enter the following command:
```
cd /
```
This command changes the current working directory to the root directory, which is the top-level directory in the file system hierarchy.
HOW to get the current position within the file
To get the current position within a file in C++, you can use the tellg() function for input files and tellp() function for output files. These functions return the current position in the stream as a streampos object. Here's an example:
```
#include <fstream>
#include <iostream>
int main() {
std::ifstream input_file("example.txt");
if (!input_file.is_open()) {
std::cerr << "Failed to open file\n";
return 1;
}
// Get current position in file
std::streampos pos = input_file.tellg();
std::cout << "Current position: " << pos << '\n';
// Do some reading and move position
char c;
input_file >> c;
pos = input_file.tellg();
std::cout << "New position: " << pos << '\n';
input_file.close();
return 0;
}
```
This program opens a file "example.txt", gets the current position using tellg(), reads one character from the file, and gets the new position again. The output will show the two positions in the file.
