计算器源代码？
这个代码可以实现计算器功能
#include "stdafx.h"
#include
#include
using namespace std;
void add()
{
printf("输入要计算的加数（例如a b）\n");
int adda=0, addb=0,addc=0;
cin >> adda;
cin >> addb;
addc = adda+addb;
cout <
}
void substraction()
{
printf("输入要计算的减数（例如a b）\n");
int suba = 0, subb = 0, subc = 0;
cin >> suba;
cin >> subb;
subc = suba-subb;
cout < } void multiplication() { printf("输入要计算的乘数（例如a b）\n"); int mula = 0, mulb = 0, mulc = 0; cin >> mula; cin >> mulb; mulc = mula*mulb; cout < } void division() { printf("输入要计算的除数（例如a b）\n"); int dsa = 0, dsb = 0, dsc = 0,dsd=0; cin >> dsa; cin >> dsb; dsc = dsa/dsb; dsd = dsa%dsb; cout < } void operation()//运算函数 { printf("输入数据选择做那种运算\n"); printf("输入0选择退出，1做加法，2做减法，3做乘法，4做除法（保留余数）\n"); int operatione = 0; cin >> operatione; cout << endl; try { if (operatione == 1) { //加法 add(); } else if (operatione == 2) { //减法 substraction(); } else if (operatione == 3) { //乘法 multiplication(); } else if (operatione == 4) { //出发 division(); } else if (operatione == 0) { exit(0); } else { throw 1; } } catch (int i) { cout << "输入错误" << endl; } operation(); } int main() { printf("欢迎使用本计算器"); operation(); return 0; }
