推 ric2k1:呼叫 clearScreen 為什麼傳入 screen[][NUM_COLUMN] 呢? 12/02 23:57
→ ric2k1:傳 screen 就好了吧? 請 review 一下 lecture note #4... 12/02 23:57
→ james0419:那老師關於return type 要怎麼寫? 12/03 11:08
我把改過的程式碼貼在這裡
char *const* clearScreen(char [][NUM_COLUMN]);
char*const * (*move[4])(char[][NUM_COLUMN],int , int)={downLeft,downRight,upRight,upLeft};
char*const * downLeft(char[][NUM_COLUMN],int, int);
char*const * downRight(char[][NUM_COLUMN],int, int);
char*const * upLeft(char[][NUM_COLUMN],int, int);
char*const * upRight(char [][NUM_COLUMN],int ,int);
......
char*const * downRight(char a[][NUM_COLUMN],int x,int y){ //for DR move
extern char**screen;
if(a[x][y+1]=0){ //If the string comes to an end
clearScreen(screen[][NUM_COLUMN]);
a[x+1][y+1]=a[x][y];
a[x+1][y+2]=0;
}
}
//end
error message:
