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，是蹰虞吃遂华氏还是摄氏，然后用公式转化while(1){printf("\n******************忮氽阝另***********************\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
