Reset C int array to zero : the fastest way?
...imized by hand.
memset(myarray, 0, sizeof(myarray)); // for automatically-allocated arrays
memset(myarray, 0, N*sizeof(*myarray)); // for heap-allocated arrays, where N is the number of elements
By the way, in C++ the idiomatic way would be to use std::fill (from <algorithm>):
std::fill(...

Why is C so fast, and why aren't other languages as fast or faster? [closed]
...ere is no overhead, but that means that the programmer needs to be able to allocate memory and free them to prevent memory leaks, and must deal with static typing of variables.

>>> x = np.arange(n)

Zero-cost allocations
A view does not take any additional memory. Thus, these declarations are instantaneous:
# New axis
x[np.newaxis, ...]
# Broadcast to specific shape
np.broadcast_to(x, (reps, n))
Forced allocation
