c++语言编写的计算器程序，可以实现加减乘除，不过不支持双位数，使用堆栈编写，含有中缀表达式到后缀表达式的转换。-c++ language calculator program, Math can be achieved, but does not support double-digit, use the stack preparation, with infix expression to postfix expression converter.

采用后缀式实现计算器功能，能够识别括号和判断优先级-Achieved using postfix calculator function, able to identify and determine the priority of parentheses

利用堆栈实现计算器的功能，并把输入计算式表达成后缀表达式的形式-Use the calculator function stack implementation, and to enter into a form of expression formula postfix expressions

基于C++的计算器。先把所有数据和字符postfix输出再进行计算。内附queue和functions的packet。-Based C++ calculator. All data and character first and then calculated postfix output. Queue and functions included in the packet.
