If I have a multi-line string C++11 string constant such as

R"""line 1
line 2
line3"""
Is it defined what character(s) the line terminator/separator consist of?

This is an example to illustrate my question which involves some much more complicated code that I can't post here.

#include <stdio.h>
int main()
{
int a = 0;
for (int i = 0; i < ...

This question is motivated by me implementing cryptographic algorithms (e.g. SHA-1) in C/C++, writing portable platform-agnostic code, and thoroughly avoiding undefined behavior.

Suppose that a

Here is the test program:

std::cout << "slope is " << slope &lt...

As far as I understand - generic lambdas are transformed into objects of local scope structs with templated operator(). This makes generic lambda very powerful and easy to use tool. On the other ha...

As I understood in C++11 decltype(expression) is used to deduce the exact same type of the given expression. But when the expression is put into parentheses itself, then the deduces type is lvalue

Let's say I have an array of integers defined like that:

static const int IntArray[] = {1, 5, 10, 12, 17};
Is there a way to the minimum or maximum value at compile time?

I wrote these two solutions for Project Euler Q14, in assembly and in C++. They are the same identical brute force approach. The assembly solution was assembled with

I have an issue in which the size of the string is effected with the presence of a '\0' character. I searched all over in SO and could not get the answer still.

Here is the snippet.

I was looking at some C++ code and found the following construct:

if('A' == 0x41) {
// ...
} else if('A' == 0xc1) {

} else {

}
I get a Visual Studio warning saying:

I was browsing some C++ code, and found something like this:

(a + (b & 255)) & 255
The double AND annoyed me, so I thought of:

(a + b) & 255
(a and b are 32-bit unsigned integers)

I

I'm using an SDK for an embedded project. In this source code I found some code which at least I found peculiar. In many places in the SDK there is source code in this format:

#define ATCI_IS_LOWER(

I argued with a friend the other day about those two snippets. Which is faster and why ?

value = 5;
if (condition) {
value = 6;
}
and:

if (condition) {
value = 6;
} else {
value = 5;...
