Question

输入一个华氏温度．要求输出摄氏温度．公式为c=5/9(F-32)输出要有文字说明，取2为小数．

Answer 1

摄氏温度计读数 = (华氏温度计读数 - 32）将乘括号内的值5再除以9

你没有具体数值，无法计算，更谈不上取2位小数！

Answer 2

//
华氏温度与摄氏温度对照表
#include
#include
int
main()
{
float
fahr
=
0,cels
=
0;
int
low
=
0,max
=
300,step
=
20;
printf
("\t=========本程序输出华氏和摄氏的温度对照！==========\n\t2006-12-30\n");
fahr
=
low;
printf
("\n\n华氏温度：
摄氏温度：\n--------
--------\n");
for
(;fahr
<=
max;)
{
cels
=
5.0
/
9.0
*
(fahr
-
12);
printf
("%.0f\t\t
%6.2f\n",fahr,cels);
fahr
+=
step;
}
system("pause");
return
0;
}

Answer 3

// 华氏温度与摄氏温度对照表

#include<stdio.h>
#include<stdlib.h>

int main()
{
float fahr = 0,cels = 0;
int low = 0,max = 300,step = 20;

printf ("\t=========本程序输出华氏和摄氏的温度对照！==========\n\t2006-12-30\n");

fahr = low;
printf ("\n\n华氏温度： 摄氏温度：\n-------- --------\n");
for (;fahr <= max;)
{
cels = 5.0 / 9.0 * (fahr - 12);
printf ("%.0f\t\t %6.2f\n",fahr,cels);
fahr += step;
}
system("pause");
return 0;
}

Answer 4

#include "stdio.h"

int main()
{
float c,f;
printf("Please Enter F");
scanf("%f",&f);
c=(f-32)*5/9;
printf("C is %.2f",c);
return 0;
}

Answer 5

楼主啊,你没有限定语言啊..那我也来用PASCAL来回答回答
c=5/9(F-32)
VAR C,F:INTEGER;
BEGIN
WRITELN('PLEASE INPUT F`TEMPERATURE');
READLN(F);
c:=5/9*(F-32);
WRITELN('IT IS ',C,' `C');
END.
