[Dev-C++] How i convert a char matrix to int matrix ?

[<hu...@cl...>]

Hei all,
<br>i have this matrix :
<br>
<br>char matrix[5][5] =
<br>{{'0','0','0','0','0'},
<br>{'0','0','0','0','0'},
<br>{'0','0','0','0','0'},
<br>{'0','0','0','0','0'},
<br>{'0','0','0','0','0'}
<br>};
<br>
<br>and i have this function :
<br>
<br>void show_matrix(int m[5][5))
<br>{
<br> int i,j;
<br> 
<br> for(i=0;i<5;i++)
<br> {
<br>  for(j=0;j<5;j++)
<br>  {
<br>    printf("%c ",m[i][j]);
<br>  }
<br>  printf("\n");  
<br> }  
<br>}
<br>
<br>this function receives a int matrix and i have a char matix, 
<br>how i call this function with a char matrix ??
<br>
<br>

Simple - you can't since a char and an int have different sizes.

Do not convert. Declare the matrix as an int array:

int main(int argc, char* argv[])
{
         int matrix[5][5] = {'0','0','0','0','0',
         '0','0','0','0','0',
         '0','0','0','0','0',
         '0','0','0','0','0',
         '0','0','0','0','0'};

         show_matrix(matrix);
         system("pause");
         return 0;
}

void show_matrix(int m[5][5])
{
         int i,j;

         for(i=0;i<5;i++)
         {
                 for(j=0;j<5;j++)
                 {
                         printf("%c ",m[i][j]);
                 }
                 printf("\n");
         }
}

The only way to do it, if you can't modify one of the objects, is to
allocate a matrix of this kind:

int matrix_int[5][5] = {
   {matrix[0][0], matrix[0][1], // ... and so on

but you have to create a new object, it is possible only if you know that
your matrix is small (5x5 makes cheap the job, for a 100x100 I'd think a
better solution). Obviously you can allocate an empty object and then
populate it with a for, treating the char matrix as a vector; if you
accept this solution, I suggest you create a proxy function (for instance
void show_char_matrix (...)) which allocate the matrix_int object and then
call show_matrix.

Hope I helped
