你的bill、times這兩個變量都沒有初始值；定義的caculate方法也沒有調(diào)用

自定義計算函數(shù)需要添加返回值???return?bill; int?main()????{??????????????scanf("%d",&distance);??printf("請輸入打車距離");?????????times?=?2?;?????????????????????//打車次數(shù)???????????????????sum?=?caculate(distance)*times+times;?????????//總金額+2塊起步費??????????????printf("應(yīng)該花費%d",sum);??????????????return?0;????}
