Why is there no std::stou?
...n stoul and a hypothetical stou would be a check that the result is in the range of unsigned:
unsigned stou(std::string const & str, size_t * idx = 0, int base = 10) {
unsigned long result = std::stoul(str, idx, base);
if (result > std::numeric_limits<unsigned>::max()) {

Can I convert long to int?
...method
But it will throw an OverflowException if it the value is outside range of the Int32 Type.
A basic test will show us how it works:
long[] numbers = { Int64.MinValue, -1, 0, 121, 340, Int64.MaxValue };
int result;
foreach (long number in numbers)
{
try {
result = Convert.ToInt32...
How do you calculate the average of a set of circular data? [closed]
.... The first line computes the relative angle of a with respect to b in the range [-180, 179], the second computes the middle angle from that. I'd use b + diff/2 instead of a - diff/2 for clarity.

Actually there is a good excuse. You're using Boost.Range's algorithms, which are much nicer ;)

Usage of sys.stdout.flush() method
...ider the following simple Python script:
import time
import sys
for i in range(5):
print(i),
#sys.stdout.flush()
time.sleep(1)
This is designed to print one number every second for five seconds, but if you run it as it is now (depending on your default system buffering) you may not s...
convert double to int
...etc - although you'll still need a cast afterwards.
Don't forget that the range of int is much smaller than the range of double. A cast from double to int won't throw an exception if the value is outside the range of int in an unchecked context, whereas a call to Convert.ToInt32(double) will. The r...
C++ Erase vector element by value rather than by position? [duplicate]
... It moves all values not equal to the value passed to the beginning of the range [begin,end). With your example in the question you'd get 5,9,2,0,7,7. As remove() however returns an iterator to the new end, vec.erase() can remove the obsolete elements (i.e. the second 7 here) if that is needed.
