Q2. for loop statement is terminated by symbol ___________

Show Answer
Ans. Semicolon(;)

Q3. What is the difference between break and continue statements?

Show Answer
Ans. break statement terminates the loop as the condition matches. for example.

a=5

while a>0:

   a=a-1

   if a==3: #as this condition matches it terminates the loop

      break

   else:

      print(a)

Output : 4


Continue statement is used to skip a particular condition. for example

a=5

while a>0:

   a=a-1

   if a==3: #as this condition matches it goes to the next condition of the loop

      continue

   else:

      print(a)

Output : 
4
