Question

what happens in while-loop if the resulting value of the condition is true?

Answer 1

if condition is true the code inside the loop is executed again and again till then the the is not becomes false or break statement is not executed

Answer 2

I will give you some examples:
Python-

while True:
##Do stuff


that example will occur forever until you say 'break'

x=5
while x > 0:
x = x - 1

That will end once 'x' variable reaches 0.

There are many similar examples for different programming languages.
