How to display the numbers that are in the text in the file?

Question

C++ / C#

There are numbers in the text, they need to be displayed, how to do this?

ofstream file;
file.open("C:/Users/Desktop/text.txt");
  ofstream file;file << "8ы м0л0дцы! ТекстТекстТекстТекст 01 01";
  file.close();

  char buff[80];
  ifstream fin("C:/Users/Desktop/text.txt");

  fin >> buff;
  cout << buff << endl;

  fin.getline(buff, 80); 

  fin.close();
  cout << buff << endl;

This method does not work, swears at ">>" data type float/int/double

Answer 1

Try checking each character with
if (typeid(std::int)==typeid(yourVariable)
{
}
