1, the problem to avoid repetition in the output is to determine whether random numbers and random symbols are all the same. All the same then break;
2, custom, M for custom number of copies, n to customize the number of questions per title

for (j=0;j<m;j++)
{
for (i<0;i<n;i++)
{
A=rand ()%100; Generates 100 or less random numbers
B=rand ()%100;
D=rand ()%4; Generating random operators
Switch (d)
{
Case 0:
cout<<a<< "+" <<b<< "=" <<endl;
Break
Case 1:
cout<<a<< "-" <<b<< "=" <<endl;

Break
Case 2:
cout<<a<< "*" <<b<< "=" <<endl;
Break
Case 3:
cout<<a<< "/" <<b<< "=" <<endl;
Break

}
}
}

3, control parameters: whether there is a multiplication method, whether there are parentheses, the range of values, plus or minus negative numbers, Division has no number, whether to support fractions (true, false), whether to support fractional (accurate to how many bits)
The interval of each line in the print can be adjusted ....
Output selection Hint: Select the multiplication method. Plus minus have negative numbers
Select output, before output, judge whether the condition can be satisfied. Plus or minus a negative number to judge a>b, then output;
