Question

Write an if statement that assigns 0 to \(x\) if \(y\) is equal to 20.

Short answer

Answer: Follow these steps to create an if statement that fulfills this condition: 1. Define the variables x and y, assigning any value to y for testing purposes. To test if the if statement works properly, assign the value 20 to y. 2. Write an if statement to check if y is equal to 20, using the == operator to compare y to the value 20. 3. Inside the if statement block, if the condition is true (i.e., y is equal to 20), assign the value 0 to the variable x. 4. Finally, run the code and observe the output. Test with different values of y to ensure the if statement is working correctly. If y is equal to 20, the value of x should be 0; otherwise, x's value will remain unchanged from its initial assignment.

Step-by-step solution

Define the variables

Begin by defining \(x\) and \(y\) variables. You can assign any value to \(y\) for testing purposes, but to see if the if statement works properly, assign \(y\) with the value 20.

Write the if statement

Create an if statement to check if \(y\) is equal to 20. In this case, use the == operator to compare \(y\) to the value 20.

Assign value to x inside the if statement

If the if statement is true, which means that \(y\) is equal to 20, assign the value 0 to the variable \(x\). To do this, insert the assignment statement inside the if statement block.

Test the code

Run the code and observe the output. If \(y\) is equal to 20, the value of \(x\) should be 0. Otherwise, the value of \(x\) will remain unchanged from its initial assignment. Test with different values of \(y\) to ensure the if statement is working correctly.
