Initialize a float array on construction

Question

Is there a way in C++ to construct a float array initializing it\'s values?

For example, i do:

float* new_arr = new float[dimension];
for(unsigned int i          


        

Answer 1

float* new_arr = new float[dimension]();

Answer 2

In this particular case (all zeroes) you can use value initialization:

float* new_arr = new float[dimension]();

Instead of explicitly using new[] you could use a std::vector<float> instead:

std::vector<float> new_vec(dimension, 0);
