What is the difference between a reference type and value type in c#?
...t. If PO boxes doesn't do it for you, try a hashtable or dictionary or an array or something similar.
Thus, when you do something like:
var a = "Hello";
the computer will do the following:
allocate memory (say starting at memory location 1000 for 5 bytes) and put H (at 1000), e (at 1001), l (...
Realistic usage of the C99 'restrict' keyword?
...vectors of numbers in memory, and I have the following code:
void MultiplyArrays(int* dest, int* src1, int* src2, int n)
{
for(int i = 0; i < n; i++)
{
dest[i] = src1[i]*src2[i];
}
}
The compiler needs to properly handle if dest, src1, and src2 overlap, meaning it must do o...
Why is a combiner needed for reduce method that converts type in java 8

.stream()
.reduce("",
(accumulatedStr, str) -> accumulatedStr + str); //accumulator

Task.WaitAll(ids.Select(i => DoSomething(1, i, blogClient)).ToArray());
On the other hand, the above code with WaitAll also blocks the threads and your threads won't be free to process any other work till the operation ends.
Recommended Approach
I would prefer WhenAll which will pe...
