覺得好就給個采納吧-.親#include double f2c(double num){return 5.0*(num-50)/9.0+10;}double c2f(double num){return 9.0*(num-10)/5.0 +50;}int main(){char c;double num;c = getchar();scanf("%lf",&num);if(c ...什么意思大概解釋一下唄攝氏溫度與華氏溫度的換算式是：5(tºF- 50)=9(tºC-10º)式中tºF--華氏溫度，tºC--攝氏溫度。#include double f2c(double num)//華氏轉(zhuǎn)攝氏溫度{return 5.0*(num-50)/9.0+10;}double c2f(double num)//攝氏溫度轉(zhuǎn)華氏溫度{return 9.0*(num-10)/5.0 +50;}int main(){char c;double num;c = getchar();//獲取第一個輸入字符scanf("%lf",&num);if(c == 'F')//輸入華氏溫度，需轉(zhuǎn)成攝氏溫度printf("C %.2f\n", f2c(num));if(c == 'C')printf("F %.2f\n", c2f(num));return 0;}要是用這個公式呢？C=(F-32)*5/9
