This article mainly introduces "how C++ realizes the score calculator". In the daily operation, I believe that many people have doubts about how C++ realizes the score calculator. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "how to realize the score calculator on C++". Next, please follow the editor to study!

Problem description and functional requirements

1. Each function of the score calculator program can be listed with menu options, and users can select the corresponding menu items according to their needs, thus executing different subroutines to complete the corresponding functions.

2. The operator overloading function is added so that the designed fractional calculator can carry out four operations-power operation-logic operation. Four operations & power operations can be listed with menu options, and users can choose the corresponding operations according to their needs.

3. The program has the function of judging. When there is an illegal input (such as zero denominator, etc.), it can give a prompt message and exit the operation.

4. Fractions can be reduced to decimal and fractional

5. The function of logic function is designed so that it can be compared logically, such as the logical comparison of greater than and less than.

6. Design the digital selection function program, the user can input the numeric key to choose to carry on four operations-power operation or logical comparison, and the result is TRUE or FLASE.

7. the interface is required to be clear and easy to operate.

Code implementation with comments

Don't talk nonsense, direct code, welcome to correct.

Everyone CV may have incompatibility, you can reply with me Didi as much as possible to solve the problem.
