操作方法
首先打开VC++
文件》》新建
新建一个C++文档
声明头文件和变量 #include<stdio.h> char cmd; float temperature;
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;
