The built-in calculator features in Windows systems are useful for many users who buy or sell goods online, and in our familiar Win7 and XP systems, we usually find calculators in the initial-program-attachment, but since Win8 cancels the Start menu, This makes a lot of net buys a clan and shop merchant is vexed unceasingly
First, if you are entering the WIN8 start screen, then you may wish to use the following method steps to find the Win8 to take
The first glimpse of the MAC version of the original Calculator application, you may find that the calculator function is very simple, but in fact it also built two other calculator mode, respectively, is a scientific calculator and programmer calculator.

This time, we use C ++ for the development language and Qt for the development environment. There is nothing to explain when selecting C ++.
Why Qt is selected
Qt is free of charge
Qt is a cross-platform development that can be released on multiple platforms, such as Windows, Linux, and Symbian ).
Popular technologies (such as Layout and XML) and architectures used in Qt development. After learning Qt, it is easier to get started in other environments.
Installation Steps

[LeetCode] Basic Calculator IIBasic Calculator II
Implement a basic calculator to evaluate a simple expression string.
The expression string contains only non-negative integers, +,-, *, and/operators. The integer division shoshould truncate toward zero.
You may assume that the given expression is always valid.
Some examples:
"3+2*2" = 7" 3/2 " = 1" 3+5 / 2 " = 5
The pure javascript code implements the calculator function. Next, let's share with you the calculator program compiled with pure javascript code, if you need a calculator program, you can share it with me today. it can be used in many industries, such as renovation budget and loan interest rates.
First, let's take a look at the effect:

The Set calculator assists Java in processing grouping and summarizing structured text, and java structuring
Using Java to group and summarize style files may cause the following troubles:
1. files are not databases and cannot be accessed using SQL. When the grouping and summary expressions change, you can only rewrite the code. To implement flexible expressions, You need to parse and evaluate dynamic expressions by yourself. The programming workload
such as 1-2 * ((60-30 + ( -40/5) * (9-2*5/3 + 7/3*99/4*2998 +10 * 568/14))-( -4*3)/(16-3*2)), the user input must be Self-analysis inside the (), +,-, *,/symbols and formulas, the result of the operation, the results must be consistent with the results of the actual calculator.
