c++ - Help with type conversion error -


when try compile program, following error:

main.cpp: in function ‘int main()’: main.cpp:67: error: cannot convert ‘int (*)[(((long unsigned int)(((long int)mapsizey) -      1)) + 1u)]’ ‘int (*)[10]’ argument ‘3’ ‘void initializemap(int, int, int (*)[10])’ main.cpp:68: error: cannot convert ‘int (*)[(((long unsigned int)(((long int)mapsizey) - 1)) + 1u)]’ ‘int (*)[10]’ argument ‘3’ ‘void paintmap(int, int, int (*)[10])’

my code looks this: 

#include <iostream> using namespace std;  void initializemap(int mapsizex, int mapsizey, int map[][10]) {     // map details:     // 0 = # (wall)     // 1 = space (free space)     // 2 = x (player)      for(int x = 0; x < mapsizex; x++)     {         map[x][0] = 0;     }      for(int y = 0; y < (mapsizey - 2); y++)     {         map[0][y] = 0;          for(int x = 0; x < (mapsizex - 2); x++)         {             map[x][y] = 1;         }          map[mapsizex][y] = 0;     }      for(int x = 0; x < mapsizex; x++)     {         map[x][mapsizey - 1] = 0;     } }  void paintmap(int mapsizex, int mapsizey, int map[][10]) {     for(int y = 0; y < mapsizey; y++)     {         for(int x = 0; x < mapsizex; x++)         {                switch(map[x][y])             {                 case 0:                     cout << "#";                     break;                  case 1:                     cout << " ";                     break;                  case 2:                     cout << "x";                     break;              }              cout << map[x][y];         }         cout << endl;     } }  int main() {     int mapsizex = 10;     int mapsizey = 10;     int map[mapsizex][mapsizey];     initializemap(mapsizex, mapsizey, map);     paintmap(mapsizex, mapsizey, map);      cout << endl << endl;      return 0; }

i've spent hour trying solve issue , twenty minutes searching solution. can of me out?

c++ not support variable-length arrays, map in code. however, compilers may support non-standard extension. however, won't compatible function expecting "standard" array.

if make mapsizex , mapsizey constants, should work.
