In my code I have:
struct datapoint
{
double energy;
double probability;
};
Which is later put into a vector like so:
std::vector<datapoint> spectrum(71,0);
spectrum[0].energy = 0.937729;
spectrum[0].probability = 0.0022582628449311468;
spectrum[1].energy = 1.875458;
spectrum[1].probability = 0.0033531784328108922;
...
However, at compile time, for the line
std::vector<datapoint> spectrum(71,0);
I receive the error
/usr/lib/gcc/x86_64-redhat-linux/4.4.6/../../../../include/c++/4.4.6/bits/stl_vector.h: In member function âvoid std::vector<_Tp, _Alloc>::_M_initialize_dispatch(_Integer, _Integer, std::__true_type) [with _Integer = int, _Tp = datapoint, _Alloc = std::allocator<datapoint>]â:

I'm a bit confused as I have done this before.
