1、首先打开VC++
2、文件》》新建
3、新建一个C++文档
4、声明头文件和变量
#include<stdio.h>
char cmd;
float temperature;
5、主要代码，先进行选择，是华氏还是摄氏，然后用公式转化
while(1)
{
printf("\n*****************************************\n");
printf("\n| Please select one of convertions: |\n");
printf("| c: Convert Celsius to Fahrenheit |\n");
printf("| f: Convert Fahrenheit to Celsius |\n");
printf("| q: Quit |\n");
printf("\n*****************************************\n");
scanf("%c",&cmd);
switch (cmd)
{
case 'c':
{
printf("\n*****************************************\n");
printf("\n| Please input Celsius temperature: |\n");
scanf("%f",&temperature);
printf("\n| The Fahrenheit temperature is:%6.3f|\n",temperature*1.8+32);
printf("\n*****************************************\n");
break;
}
case 'f':
{
printf("\n*****************************************\n");
printf("\n Please input Fahrenheit temperature: |\n");
scanf("%f",&temperature);
printf("\n The Celsius temperature is : %6.3f |\n",5*(temperature-32)/9);
printf("\n*****************************************\n");
break;
}
case 'q':
{
break;
}
default:
{
printf("Your Command Error!temperatureut Again\n");
}
}
getchar();
if(cmd=='q')
break;
printf("\n Please input any key to use again: \n");
getchar();
}
return 0;
6、运行结果
