write a program that ask the user to enter an integer and deter mines whether it id divisible by 7 and 4 .whether it id divisible by 7 or 4 .whether it id divisible by 7 or 4 but not both

for example . if your input is 28 , the output should be :
Is 28 divisible by 7 and 4 ? False
Is 28 divisible by 7 or 4 ? True
Is 28 divisible by 7 or 4 , but not both ? False

boolean is_divisible(int i) 
{
  if ((i % 7 == 0) && (i % 4 == 0))
     return false; // Case when i is divisible by both 
  if ((i % 7 == 0) || (i % 4 == 0))
     return false; // Case when i is divisible by only 7 or 4 not both 
  else 
     return true; // Case when i is not divisible by 7 or 4 or both, seems question is wrong so making this assumption.

I can not compile

template 
int parallel_sum(const RAIter beg, const RAIter end) {
 const auto len = end-beg;
 if(len < 1000) return std::accumulate(beg, end, 0);

 const RAIter mid = beg + len/2;
 auto handle = std::async(std::launch::async, parallel_sum, mid, end);
 const int sum = parallel_sum(beg, mid);
 return sum + handle.get();
}

int main() {
 std::vector v(10000, 1);
 std::cout 

using "g++ -Wall -std=c++11", but running it I get terminate called after throwing an instance of 'std::system_error' what(): Unknown error -1
Aborted (core dumped)

This code compiles on MSVC but not on G++ :

template
class B
{
public:
 static void SomeMethod()
 {
 A::SomeMethod();
 }
};

class A
{
public:
 static void SomeMethod();
};

void test()
{
 B::SomeMethod();
}

The error with g++ is :

test.cpp: In static member function "static void B::SomeMethod()":
test.cpp:7:3: error: "A" has not been declared

Is there is a option to indicate to g++ to evaluate the template functions only when a specialization is called, and not before ?

I know a slot will be of 0.5ms and useful symbol duration is 66.67micro sec. And if I divide them i.e (0.5ms)/(66.67 micro sec) the result will be 7.49. Can i assume it as normal symbol?? If so what will be the similar calculation for extended symbol??

For eMBMS, there are 2 kinds of subcarrier configurations, 15kHz and 7.5kHz, however, I found that there is no information in broadcast information(MIB/SIB) to tell me which kind of cell the target cell is.

Does anyone know how to find the subcarrier configuration of eMBMS in LTE?
