Question

Write code to generate a random number between 0 and 100 (inclusive) in a high school computer science class.

a) int randomNumber = (int)(Math.random() * 101);
b) random_number = random(0, 100)
c) random_number = random(1, 101)
d) num = random.randint(0, 100)

Answer 1

To generate a random number between 0 to 100, use 'int randomNumber = (int)(Math.random() * 101);' in Java or 'num = random.randint(0, 100)' in Python.

Step-by-step explanation:

The question involves generating a random number between 0 and 100 (inclusive). There are multiple ways to do this across different programming languages. Based on the code snippets provided:

• Option a) int randomNumber = (int)(Math.random() * 101); could be used in Java, where Math.random() generates a double >= 0.0 and < 1.0, which is then multiplied by 101 to scale it to the desired range and cast to an integer.
• Option b) random_number = random(0, 100) resembles the syntax for some other languages or custom functions, which directly specify the inclusive range. It depends on the environment whether the end value 100 is included or not.
• Option c) random_number = random(1, 101) is incorrect for the requirement as it does not include 0 and goes one number too high if the end number is inclusive.
• Option d) num = random.randint(0, 100) could be correct if using Python's random module, where randint is inclusive of both endpoints.

The correct options depend on the programming environment and language being used, but generally, options a) and d) are correct for Java and Python respectively, for generating a random number ranging from 0 to 100 inclusive.
