Understanding If Statements and Relational Operators

The video tutorial covers the use of if statements and relational operators in programming. It demonstrates a program that categorizes temperature inputs as freezing, cold, warm, or hot. The tutorial also includes a number comparison application using relational operators. It concludes with a summary of relational and logical operators, encouraging viewers to experiment with these concepts.

What is the primary purpose of relational operators in programming?

• To store data in variables

• To test the values of numbers

• To perform arithmetic operations

• To print output to the console

Which function is used to convert a string input to an integer in Python?

• int()

• input()

• float()

• str()

What will the program print if the temperature input is -5?

• It is cold

• It is warm

• It is freezing

• It is hot

If the temperature is 15, what will the program output?

• It is cold

• It is hot

• It is freezing

• It is warm

What is the output when the first number is 56 and the second number is 6?

• First is not the biggest

• First is biggest

• Both numbers are equal

• Second is biggest

What should the program do if both numbers entered are the same?

• Print 'First is not the biggest'

• Print 'First is biggest'

• Print 'Both numbers are equal'

• Print 'Second is biggest'

Which relational operator is used to check if two values are not equal?

• >=

• <=

• !=

• ==

What logical operator is used to check if a value falls within a specific range?

• xor

• not

• and

• or

Which of the following is NOT a relational operator?

• ==

• >=

• &&

• <

What is the purpose of the 'or' logical operator?

• To negate a condition

• To compare two numbers

• To check if at least one condition is true

• To check if both conditions are true
