下面这段代码中的这行item=*(maze+(i*col_size+j));代码不懂啥意思。怎么就输出一个item就能输出全部行和列了。void print_maze(char *maze,int row_size,int col_size){ int i; int j; char item; for(i=0;i<row_size;i++){ for(j=0;j<col_size;j++){ item=*(maze+(i*col_size+j)); printf("%c ",item); } printf("\n"); printf("\n"); }}void main(void){ // 示例迷宫 char maze[9][9]={ {'#','#','#','#','#','#','#','#','#'}, {'#','@','#','#','@','@','@','@','#'}, {'#','@','@','@','@','#','#','#','#'}, {'#','@','#','#','@','@','@','@','#'}, {'#','@','@','@','#','#','#','#','#'}, {'#','#','#','@','@','@','@','@','#'}, {'#','#','#','#','#','@','#','@','#'}, {'#','#','#','#','#','@','#','@','#'}, {'#','#','#','#','#','#','#','#','#'},}; print_maze(&maze[0][0],9,9); }
