: 我寫
: double x1, y1, x2, y2, x3, y3 x4, y4, x5, y5, x6, y6, x7, y7, x8, y8;
:
: scanf("%lf %lf %lf %lf %lf %lf %lf %lf", &x1, &y1, &x2, &y2, &x3, &y3, &x4, &y

: 為什麼輸入不進去R?

: 直接輸入數字沒問題 複製（）就GG
本來在想迴圈怎麼寫
後來想不到
之後改成這樣就過了
double x1, y1, x2, y2, x3, y3, x4 ,y4;
scanf("(""%lf"", ""%lf"")" ", ""(""%lf"", ""%lf"")" ", ""(""%lf"", ""%lf"")"
", ""(""%lf"", ""%lf"")" , &x1, &y1, &x2, &y2 , &x3, &y3, &x4, &y4);
double x5, y5, x6, y6, x7, y7, x8, y8;
scanf(" (""%lf"", ""%lf"")" ", ""(""%lf"", ""%lf"")" ", ""(""%lf"", ""%lf""
)" ", ""(""%lf"", ""%lf"")" , &x5, &y5 , &x6, &y6, &x7, &y7, &x8, &y8);
完全不懂原理==
