We solved the basic function and basic setting parameters according to the homework given by teacher Feng:

1) Number of topics (requirements for individual projects)

2) range of values (requirements for individual projects)

3) Maximum number of operators in the topic

4) Whether there is a multiplication method in the question

5) There are no negative numbers in the topic

We have two teams to complete this assignment, our team is mainly responsible for the following functions:

1) public void Build_nomul_nodiv_nominus function

2) public void Build_mul_div_minus function

3) private string Getstr2 function

1. Main Page

2. Overall design

3. Function code
