The second supplement to the 30-arithmetic problem

Requirement 1: The topic avoids repetition.

The results are checked, and each question is accessed, the newly generated topics are matched, and the duplicates are removed.

Lele: IO stream;

Requirement 2: Can be customized (quantity/printing method);

The number of 30 in the for () loop becomes a parameter Dingzhi from the keyboard input;

Requirement 3:

A is there a multiplication method

The parameter C is controlled: Division c=0; addition C=1; subtraction c=2; multiplication c=3;

Use if to control the user input whether to multiplication method

b whether there are parentheses

The program should be improved into mixed operation; if 0 Cout<<;else cout<<

C Range of values

Prompt statement; new parameter

The parameters A and B are controlled, and the new parameters are used as the control conditions behind the stochastic function.

D plus minus have no negative numbers

Control the contents of case 2; A>b or a<b;

E Division Remainder

Control the contents of case 0;

F Support Score (true score, false score)

Input prompt statement

True score: Result output form A/b output

Whether G supports decimals

Enter the prompt statement;

H can I adjust the interval of each line in the print?

Parameter set a "" is judged by the contents of the parameter set.
