COMP2012H The first lecture (04/09/2018)

The first lecture of COMP2012H

It’s been a really long time since I last wrote a blog. It’s like… more than a year?
And thanks to the super easy college entrance exam, I am able to study in HKUST now.
And I think it’s time to continue writing blogs to mark down some things in my daily life and especially in the computer science study. I decide to use English because all of my courses are given in english :D.

Back to today, I toke the first lecture of COMP2012H this morning and I have to say that Dr. Desmond is a great instructor. The class was so interesting. And now I would like to write something new to me.

We can use numeric_limits::min() and numeric_limits::max() to find the lower bound and upper bound of TYPE in C++.
Like what I show below.

#include 

#include    // Library limits - For numeric_limits::min() and numeric_limits::max()

using namespace std;



int main() 

{

  // Value range of short

  cout << "Lower bound of short: " << numeric_limits<short>::min() << endl;

  cout << "Upper bound of short: " << numeric_limits<short>::max() << endl;



  // Value range of int

  cout << "Lower bound of int: " << numeric_limits<int>::min() << endl;

  cout << "Upper bound of int: " << numeric_limits<int>::max() << endl;



  // Value range of long

  cout << "Lower bound of long: " << numeric_limits<long>::min() << endl;

  cout << "Upper bound of long: " << numeric_limits<long>::max() << endl;



  // Value range of long long

  cout << "Lower bound of long long: " << numeric_limits<long long>::min() << endl;

  cout << "Upper bound of long long: " << numeric_limits<long long>::max() << endl;



  // Value range of float

  cout << "Lower bound of float: " << numeric_limits<float>::min() << endl;

  cout << "Upper bound of float: " << numeric_limits<float>::max() << endl;



  // Value range of double

  cout << "Lower bound of double: " << numeric_limits<double>::min() << endl;

  cout << "Upper bound of double: " << numeric_limits<double>::max() << endl;



  // Value range of long double

  cout << "Lower bound of long double: " << numeric_limits<long double>::min() << endl;

  cout << "Upper bound of long double: " << numeric_limits<long double>::max() << endl;



  // Value range of bool

  cout << "Lower bound of bool: " << numeric_limits<bool>::min() << endl;

  cout << "Upper bound of bool: " << numeric_limits<bool>::max() << endl;



  return 0; // The program is executed successfully.
