Question

Identify when programmers use an else statement in its place to make the test answer true, to use an expression instead of a conditional statement to make the answer false, to tell the program to take a different action when the if statement answer is false, or to tell the program to give different information when the test answer is true?

1) To make the test answer true
2) To make the answer false
3) To take a different action when the if statement answer is false
4) To give different information when the test answer is true

Answer 1

Programmers use an else statement to direct a program to take a different action when the condition in an if statement evaluates to false. It is an essential part of conditional logic, allowing the program to handle both true and false cases in a controlled manner.

Step-by-step explanation:

Programmers use an else statement in conjunction with an if statement to control the flow of a program. When an if statement is evaluated and found to be false, the program doesn’t just stop; it often needs to do something else. This is where the else statement comes in – it tells the program to take a different action when the if statement answer is false.

For example, consider a program that checks if a user is over 18 years old. The if-then statement might be: “If the user is over 18, then allow access to the website.” The corresponding else statement could be: “Else, restrict access.” This allows the program to handle both situations - when the condition is true, and when it is false.

The use of else statements is vital in conditional logic, enabling programs to make decisions and execute different code paths based on various conditions.
