VC++計(jì)算器課程設(shè)計(jì)報(bào)告

1、22VC+計(jì)算器課程設(shè)計(jì)報(bào)告1.作品名稱：計(jì)算器2.本次課程設(shè)計(jì)的目的 在程序設(shè)計(jì)中，通過設(shè)計(jì)、編制、調(diào)試一個(gè)模擬計(jì)算器的程序，加深對(duì)語法及語義分析原理的理解，并 實(shí)現(xiàn)對(duì)命令語句的靈活應(yīng)用。3.主要功能實(shí)現(xiàn)計(jì)算器的功能。用戶根據(jù)程序提示，輸入數(shù)字或字符，選擇要進(jìn)行的運(yùn)算，可以進(jìn)行正弦、余弦、正切、開方、對(duì)數(shù)、加、減、乘、除、華氏溫度與攝氏度之間的換算以及平方根的運(yùn)算。4.代碼#include <process.h>#include<time.h>#define MAX 100#include <iostream.h>#include <conio.h&
