This is essentially what I'm trying to do, but not the actual source code.
namespace namespace {
int array [3];
}
namespace::array={1,2,3}
my gcc asks for an expression, and I'm not sure of what to do. Must I namespace::array[1]; each individual element?
You can only use an initializer list in a definition:
int array[3] = { 1, 2, 3 };
If you use:
int array[3];
then you need to initialize the array in a function, using
array[0] = 1;
array[1] = 2;
array[2] = 3;
Although it an odd mixture of C99 and C++, gcc allows this:
#include <string.h>
int a[3];
int main()
{
memcpy(a, (int[3]){ 1, 2, 3}, sizeof(a));
}
!
How about namespace ns { int array[3] = {1, 2, 3}; }?
There are several ways:
1) Explicitly set values for each element:
namespace ns {
int array [3];
}
ns::array[0]=1;
ns::array[1]=2;
ns::array[2]=3;
\\ or if they should contain consequtive values:
\\ for (size_t i = 0; i < 3; ++i)
\\ ns::array[i] = i + 1;
2) If you want initialize static array in place of its declaration, then you could move it initializer list as follows:
namespace ns {
int array[3] = {1, 2, 3};
}
3) Use typedef:
namespace ns {
typedef int array_t[3];
}
ns::array_t array = {1, 2, 3};
3) Also you can make some research of std::tr1::array, which may be used as such:
std::tr1::array<int, 3> arr = {1, 2, 3};
