c++ - How do you delete (or fill with specific values) a static n-dimension array? -

const int rows = 3; const int columns = 4;  void fillarray(double a[rows][columns], double value); void deletearray(double a[rows][columns]);  int main () {     double a[rows][columns];     fillarray(a, 0);     deletearray(a); } 

in c++, how delete (or fill specific values) static n-dimension array?

in c++ not use arrays. use std::vector. can use memset or std::fill fill array specific values. btw can use delete on dynamically allocated arrays not on static ones.

 memset( a, 0 ,rows * columns * sizeof( double ));  or  std::fill(&a[0][0], &a[0][0]+sizeof(a)/sizeof(double), 0);
