5 Easy Loops and Conditions Explanation in Programming

These are some loops and conditions related question which will increase your problem solving and logical thinking skills.

1. What is the Difference between a For loop and While loop?

Both Loops are entry level conditional loops which checks conditions and execute according to the conditions.

For Loop is used for Known iteration of loops where we know how many iteration this loop will execute. But while loop is use for more complex conditions where we don’t know how many time loop will be executed.

# Python
# Syntax for loops

for i in range(0, 11, 1):
    print(i)

i = 0
while i<=10:
    print(i)
    i += 1 

Above is the Basic syntax of for and while loop in python.

2. How can you print numbers from 1 to 10 using a loop?

You can choose any one loop you want, but i recommend to practice in both loops to become more skilled programmer.

# Using For Loop
for i in range(0, 11, 1):
    print(i)

# Using While Loop
i = 0
while i<=10:
    print(i)
    i += 1

3. What happens if the condition in a while loop never becomes false?

If the condition of the loop never becomes false it cause loop to execute infinite time, the loop will not stop until you terminate the instance of the code. It can cause high CPU usage by which your system can slow down and start lagging. So be careful while using loops.

How can you achieve a infinite loop in python, using while loop.

# You can achieve it by simply using True keyword in python

while True:
    print("Infinite Loop")

These two lines of code is capable of executing loop for infinite times. Try and share your experience in comment section.

4. How do you exit a loop prematurely if a condition is met?

To Exit a loop prematurely there are two keywords in python by which you can exit loop prematurely and also skip any specific iteration.

To exit a loop we can use Break statement, like this

for i in range(0, 11, 1):
    if i == 5:
        break

This above loop is matured for 10 iteration but will exit after it reaches 5 because of he if condition and break statement.

To Skip a specific iteration we can use continue statement, Like this

for i in range(0, 11, 1):
    if i == 5:
        continue

This above code will output 1, 2, 3, 4, 6, 7, 8, 9, 10

It will skip 5 because of if condition and continue statement.

5. What will be the output of a nested loop in this scenario?

for i in range(0, 11, 1):
    for j in range(0, 2, 1):
        print(i, j)

Comment the output of the code below. Thanks for reading my blog.
