Question

Write an if/else statement that assigns 0 to x when y is equal to 10. Otherwise it should assign 1 to x.

Short answer

Question: Given the value of 'y', write an if/else statement to assign 'x' either 0 or 1 depending on the given conditions. Conditions: 1) Assign 0 to 'x' if 'y' is equal to 10. 2) Assign 1 to 'x' if 'y' is not equal to 10.

Step-by-step solution

Check condition using if statement

To check if y is equal to 10, use an if statement with the condition (y == 10). If this condition is true, we will assign 0 to x.

Use else statement for other cases

When y is not equal to 10, we need to assign 1 to x. For this, we use an else statement.

Combine if and else statements

Now we simply combine the if and else statements to create the desired if/else statement. The final if/else statement should look like this: ```python if y == 10: x = 0 else: x = 1 ```

Key concepts

If Statement

An 'If Statement' is a fundamental programming concept that allows you to make decisions within your code. It serves as a conditional branch that leads your program to execute different code depending on certain conditions. For instance, if you wish to perform an action only when a particular condition is met, you use an 'If Statement'. In the context of the given exercise, the 'If Statement' checks whether the variable \( y \) is equal to 10.

• Syntax: The syntax typically involves the keyword 'if' followed by a condition within parentheses. For example, if(y == 10) checks if \( y \) is exactly 10.
• Condition: The condition is evaluated as either true or false. If true, the following block of code is executed.
• Block of code: In Python, the block of code to be executed is usually indented under the 'if' statement.

By understanding the 'If Statement', you enable your program to react to varying inputs dynamically, executing specific portions of your code when certain criteria are met.

Else Statement

An 'Else Statement' provides an alternate path within your flow of logic, when the 'If Statement' condition is not satisfied. Together, the 'If' and 'Else' statements form a complete decision-making structure within a program, handling both scenarios where a condition might or might not be true.In the exercise, if \( y \) is not 10, the 'Else Statement' assigns 1 to the variable \( x \). Here's how it works:

• Fallback Plan: The 'Else Statement' is the fallback plan that runs when the 'If Statement' fails to be true.
• Syntax: In Python, use the 'else' keyword followed by a colon and an indented block of code. For example, else: x = 1.
• No Condition: Unlike 'If', the 'Else Statement' does not require a condition to evaluate.

With this strategy, you ensure your program can handle alternate possibilities, making sure that all scenarios are covered.

Assignment Operator

The 'Assignment Operator' is a simple yet vital component in programming. It is used to store a value into a variable. In most programming languages, the symbol '=' denotes the assignment operation, allowing you to set the right-hand side value into the left-hand side variable.In the given exercise, the 'Assignment Operator' is used to set the value of \( x \) based on the condition of the 'If-Else' statement.

• Assigning Values: When you see x = 0, it means 0 is being assigned as the current value of \( x \).
• Updating Variables: You can use the assignment operator to update the value of a variable throughout your program by changing what comes after the '=' sign.
• Chaining Assignments: In some cases, multiple assignments can be made in a single line, such as a = b = c = 0.

Through the effective use of the 'Assignment Operator', you ensure that your variables are set correctly and modified as intended at various stages of your program.
