How to write a multidimensional array to a text file?
...This (a 2D array) works fine
import numpy as np
x = np.arange(20).reshape((4,5))
np.savetxt('test.txt', x)
While the same thing would fail (with a rather uninformative error: TypeError: float argument required, not numpy.ndarray) for a 3D array:
import numpy as np

What are bitwise operators?
... For example, reading an integer from four bytes:
int val = (A << 24) | (B << 16) | (C << 8) | D;
Assuming that A is the most-significant byte and D the least. It would end up as:
A = 01000000
B = 00000101
C = 00101011
D = 11100011
val = 01000000 00000101 00101011 11100011
