How to find valid values in a Range?

Question

Hello there,I'm a c# beginner.

 

I'm actually working on a project that does white-box testing.

for example,if  i write this piece of code in a textfield " if(value<4)",my program will generate the following table

 

value	Output
3	True
5	False

 

 The table will dynamically change in size depending on the conditions.

The values  3 and 5 were randomly generated.

 

Now that you got a gist of my project,i'm stuck when it comes to more than one condition.

 

For example when it comes to this " if (value >4 && value  <=10)"..

Note: i have  functions for each of these conditions  , "=", "<",">","<=",">=","!="

 

Can someone help me with this? How do i get it to give me a true value that is in the range and a false value?
