Short Answer

Expert verified
Question: Write an if statement that assigns the value 100 to a variable x when the value of another variable y is equal to 0. Answer: ```python if y == 0: x = 100 ```

Step by step solution

01

Write the if statement

To write the if statement, first start with the keyword "if" followed by the condition that y is equal to 0. In most programming languages, the equality operator is "==". ```python if y == 0: ```
02

Assign the value 100 to x

Inside the if statement block, write the assignment statement to assign the value 100 to the variable x. ```python x = 100 ```
03

Combine the steps

Now, combine the if statement and the assignment statement in a single code block. ```python if y == 0: x = 100 ``` This code checks whether the value of y is equal to 0. If the condition is true, it assigns the value 100 to the variable x. If the condition is false, nothing happens to the variable x.
