Why do C and C++ compilers allow array lengths in function signatures when they're never enforced?
... It is the same idea as the 1-D case. What looks like a 2-D array in C and C++ is actually a 1-D array, each element of which is another 1-D array. In this case we have an array with 10 elements, each element of which is "array of 20 ints". As described in my post, what actually gets passed to the...

how does array[100] = {0} set the entire array to 0?
...nd recursively applies this to aggregates).
The behavior of this code in C++ is described in section 8.5.1.7 of the C++ specification (online draft of C++ spec): the compiler aggregate-initializes the elements that don't have a specified value.
Also, note that in C++ (but not C), you can use an e...
Why is Thread.Sleep so harmful
...s for timing.
Threads are a limited resource, they take approximately 200,000 cycles
to create and about 100,000 cycles to destroy. By default they
reserve 1 megabyte of virtual memory for its stack and use 2,000-8,000
cycles for each context switch. This makes any waiting thread a
