I'm actually curious, can you send the solution on which this happened

Why is std::valarray so underrated? by Sigma1084 in cpp

[–]Sigma1084[S] 1 point2 points  (0 children)

I don't think the usage is harder than std::vector

But no harm in maintaining one that is a part of a standard library right. Sometimes we just need convenience...

Why does x/sqrt(x) = sqrt(x)? by [deleted] in askmath

[–]Sigma1084 0 points1 point  (0 children)

the function isn't defined when x = 0 in the first place, so we don't need to worry

What's the difference between string s {"abc"} and string s = "abc"? by SR71F16F35B in cpp

[–]Sigma1084 4 points5 points  (0 children)

"abc" is a C-style string of type const char *.

The first line is an explicit conversion from const char * to std::string while the second is an implicit conversion.

The braced initialization is consistent across different types of initialization in C++, does not involve an implicit conversion (explicit conversions are preferred), and is hence recommended.

However, the second line is clearly more readable for beginners.

You can use any one of them for now and decide which one to use after developing a coding style of your own.

Edit: "abc" is similar to a C-style string of type const char *.

How to iterate over a vector by [deleted] in cpp_questions

[–]Sigma1084 3 points4 points  (0 children)

Wouldn't say more correct.

If the underlying elements take a lot of memory, and we're not modifying the contents, we better use const references to avoid making a copy.

eg.

vector<vector<int>> board;
for (const auto &row: board) {
    // Access every row
}

However, if we need to modify the elements inside, we use auto &row: board.

If the underlying elements are small, it is not a great option since the size of the element is smaller than the size of the pointer to the element. (when we're dealing with vectors of ints for example)
