/*----------------------------------------------------- 程序设计：胥学辰-----绝对原创！ 设计时间：2011-10-13辰时----2011-10-13午夜。 程序功能： 1:可以对输入的两个数字进行加减剩除运算。 2:可以连续运算。例如：12-2=10，再按减等于8，可以依次减下去。 3:运算完成后显示，再按返回键可以进入最初界面，继续运算。 程序按键： 1:进入运算界面:15. 2:确定输入:14 3:加法:13 4:减法:12 5:乘法:11 6:除法:10 7:返回:9 程序缺点： 1:由于键盘有限，没有设置更改键，必须返回重新输入！ 2:暂时不能进行负数运算！ 完整版本的程序下载地址： http://www.51hei.com/f/1286411.rar ----------------------------------------------------------*/ #include<reg52.h> #define uchar unsigned char #define uint unsigned int #define ulint unsigned long int ulint m=0,m1=0;
