Clear terminal in Python [duplicate]
...
A simple and cross-platform solution would be to use either the cls command on Windows, or clear on Unix systems. Used with os.system, this makes a nice one-liner:

You cannot trust g++ 4.6.3 here with 64 bit integers on a 32 bit intel platform. a/b is computed by a call to divdi3 and a%b is computed by a call to moddi3. I can even come up with an example that computes a/b and a-b*(a/b) with these calls. So I use c=a/b and a-b*c.
The div method gives a ca...

What is the difference between “long”, “long long”, “long int”, and “long long int” in C++?
...
This doesn't necessarily mean that a long long is wider than a long. Many platforms / ABIs use the LP64 model - where long (and pointers) are 64 bits wide. Win64 uses the LLP64, where long is still 32 bits, and long long (and pointers) are 64 bits wide.
There's a good summary of 64-bit data models...
