If we're talking about C++0x you could take Ronix's example a step further and use a lambda for the predicate parameter to sort:
template<typename T>
void mfunc()
{
...
By having a public method return a TestStruct you effectively negate the privateness of it. If you want TestStruct to be private then you shouldn't return any TestStruct through public methods.
...
Maybe this is less confusing; It does the same thing:
#include <iostream>
#include <limits>
using namespace std;
int main()
{
int a;
I can help you conceptually, but without any code of your own I don't feel very motivated to write any myself.
Conceptually: read from some input one character at a time, testing whether it's...
The extraction ">>" and inserter "<<" operators both return references to their respective stream objects, meaning that the expression "cin >> a" evaluates into a reference to "cin"
It's done this...
#include <iostream>
#include <limits>
using namespace std;
int main()
{
int a;
cout << "Enter number\n";
Have you considered using a fixed-point representation?
Put loops inside your loops to make them faster:
while (true)
{
while (true)
{
while (true)
{
// uber-fast!
}
You could do that with the conditionals but the compiler will recognize the common expressions and generate code mostly equivalent to what you have already.
Or do you want to directly modify the...
With WPO turned off your main module has no knowledge of the Bla module and so the optimizer can't do certain things like find the best use of registers across module boundaries.
Since you're...
MSVC already conforms to the ISO standard for C++, however, like most C++ compilers there are non-standard extensions available for use, I doubt it would be a problem for most newcomers, however if...
it's already been said but use stringstreams:
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main()
Are you sure that's MFC and not C++/CLI? :)
cout.precision(1);
cout << fixed << a << endl;
e: I'm not quite fast enough
Yeah, somewhat confusing.
If you don't specify a "break" after some case block then program flow continues linearly, hence it "falls through" to the subsequent cases.
Perhaps the C language...
I don't think O(n^2) is right. Most (actually all, IIRC) implementations of unordered_map use hash tables and any sane hash table is going to have linear worst-case performance.
I don't like the...
Memory which is allocated on the stack or the heap can be thought of as dynamic because its allocation depends on the flow of program control.
Memory which is allocated once when the program is...
Are you expected to turn in program source code or compiled executables? If you only need to turn in the source code then simply write portable (i.e. conforming strictly to the language standard and...
Ah, thank you! That's exactly what I was looking for.
But it's not an initialization, it's an assignment?
I've been trying to find proof that this is legal in C++0x but I haven't had any success. Care to point me in the right direction?
Thanks.
Readability and debugability (is that even a word?) are rather subjective but some people (including me) find the switch statement to be more clear. However, in many cases a compiler has a better...

Since you're dealing with a ball bouncing inside of a square you don't need to worry about complex calculations involving angles of incidence and reflection, it's very straightforward in this...
So what are you more curious about: how to draw the ball, how to make it bounce randomly off of walls, or how to use MFC in general?
