C initialize array within structure

by

Here is my version:

#include <stdio.h> 

struct matrix {
  int rows;
  int cols;
  int **val;
} a = {        .rows=3,  .cols=1,
        .val = (int*[3]){ (int[1]){1},
                          (int[1]){2},
                          (int[1]){3} } },

  b = {        .rows=3,  .cols=4,
        .val = (int*[3]){ (int[4]){1, 2, 3, 4},
                          (int[4]){5, 6, 7, 8},
                          (int[4]){9,10,11,12} } };

void print_matrix( char *name, struct matrix *m ){
  for( int row=0;row<m->rows;row++ )
    for( int col=0;col<m->cols;col++ )
      printf( "%s[%i][%i]: %i\n", name, row, col, m->val[row][col] );
  puts("");
}

int main(){
  print_matrix( "a", &a );
  print_matrix( "b", &b );
}
