Produce a random number in a range using C#

You can try
Random r = new Random();
int rInt = r.Next(0, 100); //for ints
int range = 100;
double rDouble = r.NextDouble()* range; //for doubles
Have a look at

Why can't variable names start with numbers?
...ire the uses of spaces. So, basically, the following are identical:
10 V1=100
20 PRINT V1
and
10V1=100
20PRINTV1
Now suppose that numeral prefixes were allowed. How would you interpret this?
101V=100
as
10 1V = 100
or as
101 V = 100
or as
1 01V = 100
So, this was made illegal.

What is a plain English explanation of “Big O” notation?
...we have to add together 6 digits (and possibly carry a 7th). If we add two 100 digit numbers together we have to do 100 additions. If we add two 10,000 digit numbers we have to do 10,000 additions.
See the pattern? The complexity (being the number of operations) is directly proportional to the num...
