我想的比較傻，數(shù)據(jù)多了就zz了···大佬們有沒有更好的建議？（感覺自己太沙雕了）

運(yùn)行沒有問題~

for(int j = 0;j<2;j++) 這行代碼是什么意思？
2019-05-06
if(number==1||number==2||number==3) 判斷條件可以寫成? number <=3
我沒仔細(xì)看你的代碼，初學(xué)者你能實(shí)現(xiàn)這個(gè)功能就很棒啦！
2019-05-03
比你的更傻 ? 所有代碼在main函數(shù)里就實(shí)現(xiàn)了?
2019-04-22
比你的更傻子 子父類都沒用到? 哇
2019-04-04
代碼也長的跟個(gè)鴰貔一樣···
2019-04-04
main函數(shù)中間的判斷跟個(gè)傻子一樣···（太羞恥了）
