How many choices are possible when using a single IF-ELSE statement?

two possible choices
In programming , selection is implemented using IF statements . Using IF and ELSE gives two possible choices (paths) that a program can follow.

What are if-else statements used for in programs quizlet?

an if-else statement decides the execution path based on whether the condition is true or false. note: if the boolean expression evaluates to true, the statements for the true case are executed; otherwise, the statements for the false case are executed.

How do you code if?

To write an if statement, write the keyword if , then inside parentheses () insert a boolean value, and then in curly brackets {} write the code that should only execute when that value is true . That code is called the body of the if statement.

WHAT DO IF statements allow us to do?

The if statement allows you to control if a program enters a section of code or not based on whether a given condition is true or false. One of the important functions of the if statement is that it allows the program to select an action based upon the user’s input.

Use two if statements if both if statement conditions could be true at the same time. In this example, both conditions can be true. You can pass and do great at the same time. Use an if/else statement if the two conditions are mutually exclusive meaning if one condition is true the other condition must be false.

Why do we need to use if condition in our codes?

An if statement lets your program know whether or not it should execute a block of code. Comparison-based branching is a core component of programming. … Programming without if statements challenges you to think out of the box. You will have to learn other ways to structure your code, which may make it more readable.

What is the meaning of true or false?

True or false is variously said of something that must be considered as correct (true) or incorrect (false).

What is false && false?

The result of an expression using the && operator is determined based on these rules: If the left side of the expression is “falsey”, the expression will return the left side. … So in false && false , the left side is “falsey”, so the expression returns the left side, false .

What is true and true and false?

The true operator returns the bool value true to indicate that its operand is definitely true. … The true and false operators are not guaranteed to complement each other. That is, both the true and false operator might return the bool value false for the same operand.

What is true and false in Python?

Every value in Python is either True or False, numbers are True if they are not zero, and other values are True if they are not empty.
Boolean value of v1 Boolean value of v2 result (Boolean value)
True True v1 (True)
True False v1 (True)
False True v2 (True)
False False v2 (False)

Is false and false true Java?

Java has two operators for performing logical And operations: & and &&. Both combine two Boolean expressions and return true only if both expressions are true. … If they’re both true, the & operator returns true. If one is false or both are false, the & operator returns false.
