Question

my question is why if varible=0
then while varible <5
varible=varible+1
how this is posible the varible is =0 how is = varible +1 it make anoter varible .

Answer 1

variable=0 declares a variable called "variable" and stores the value 0 in it.
while variable<5 starts a while loop
and variable=variable+1 counts 0, 1, 2 etc. until it has reached 4, because the while loop executes while the value of the variable is smaller than 5.
