C++ error: “taking address of temporary array”

Question

I am trying to declare an array inside an if-statement. I wrote my code this way so that the object stays in scope once the if-block exits, but now I have a new issue: \"tak

You can use a temporary array to achieve this

int temp [] = {0,1,0,1,-4,1,0,1,0};
size_t n = sizeof(temp)/sizeof(int);

if (condition == true )
{
   maskArray = new int[n]{0,1,0,1,-4,1,0,1,0};
}

// ...

delete [] maskArray; // Free memory after use

Or simply use a std::vector

std::vector maskArray;

if( condition == true )
{
  maskArray = {0,1,0,1,-4,1,0,1,0}; // C++11 initializer_list vector assignment
}
