这是我的版本:
#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; );
}
