Description

Copy two-dimensional to a second two-dimensional array

Demo Code

#include <stdio.h>

#define ROWS 3/* www.  ja  v  a2  s .  com*/
#define COLUMNS 5

void copy2DimensioalArray(int rows, int cols, double source[ROWS][COLUMNS],

   { 2.1, 35.31, 16.35, 0.132, 11.1 } };
   double array2[ROWS][COLUMNS];

   // copy array1 to array2
   copy2DimensioalArray(ROWS, COLUMNS, array1, array2);

   // print contents of arrays
   printf("Array 1:\n");
