Question

Differentiate between break and continue statements using examples.

Answer 1

The 'break' statement alters the normal flow of execution as it terminates the current loop and resumes execution of the statement following that loop.

Example:

num = 0
  for num in range(5):
    num = num + 1
    if num == 3:
      break
    print('Num has value ' , num)
  print('Encountered break!! Out of loop')

OUTPUT:

Num has value 1
Num has value 2
Encountered break!! Out of loop

When a 'continue' statement is encountered, the control skips the execution of remaining statements inside the body of the loop for the current iteration and jumps to the beginning of the loop for the next iteration. If the loop’s condition is still true, the loop is entered again, else the control is transferred to the statement immediately following the loop.

#Prints values from 0 to 5 except 3
num = 0
for num in range(5):
  num = num + 1
  if num == 3:
    continue
  print('Num has value ' ,num)
print('End of loop')

OUTPUT:

Num has value 1
Num has value 2
Num has value 4
End of loop
