what is a variable 3f

1-- In programing variables exist in 99%(if not all) of programing languages:
2-- Think of them as little boxes that can store data
3-- some examples:
4
5-- C#
6  count = 0;
7  While true
8  {
9    count = count + 1;
10    print(count);
11  }
12  
13-- Python
14	count = 0
15	While True:
16    	count = count + 1
17        print(count)
18        
19-- as you see, both of these programs will output:
201
212
223
234
245
256
267
278
289
29...
30-- and it will keep counting till you crash the program.
31
