float?money(int?km,?int?tm)你的函數(shù)返回的是浮點(diǎn)型，但是int?shangwu,xiawu;這里定義的是整型，將這里的整型改成float?shangwu,xiawu;就可以了

把這里的代碼改成
if(tm>=25||tm<0)
????{
????printf("無(wú)效的時(shí)間格式")
????return?0;
????}
????else????????????????????????????????????????????//這里不可以加判斷條件的

printf("小明每天打車花費(fèi):%.2f\n",morning+nigh);這一行出錯(cuò)了，已經(jīng)修正，但還是錯(cuò)誤
printf("小明每天打車花費(fèi):%.2f\n",shangwu+xiawu);
