- NOT – =IF(NOT(Something is True), Value if True, Value if False)
What are the different types of if statements?
There are three forms of IF statements: IF-THEN , IF-THEN-ELSE , and IF-THEN-ELSIF .
What is if statement in C?
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.
How do if statements work?
The IF statement works by checking the expression to see whether a condition is met and returns a value based on the output obtained. For example, based on the criteria, it returns one predetermined value if the condition is found to be true and a different predefined value if the statement is found to be false.
Can you put if statements in if statements?
You can put an if statement inside another if statement.
What are the 3 arguments of the IF function?
There are 3 parts (arguments) to the IF function:
- TEST something, such as the value in a cell.
- Specify what should happen if the test result is TRUE.
- Specify what should happen if the test result is FALSE.
Can you have 3 conditions in an if statement?
If you have to write an IF statement with 3 outcomes, then you only need to use one nested IF function. The first IF statement will handle the first outcome, while the second one will return the second and the third possible outcomes. Note: If you have Office 365 installed, then you can also use the new IFS function.
How do you pass two conditions in an if statement?
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.

Why do we use while loops?
The while loop is used to repeat a section of code an unknown number of times until a specific condition is met. For example, say we want to know how many times a given number can be divided by 2 before it is less than or equal to 1.
Why are parameters useful?
Parameters allow us to pass information or instructions into functions and procedures . They are useful for numerical information such as stating the size of an object. Parameters are the names of the information that we want to use in a function or procedure. The values passed in are called arguments.
What is the structure of if else if?
The If-Else statement
The general form of if-else is as follows: if (test-expression) { True block of statements } Else { False block of statements } Statements; n this type of a construct, if the value of test-expression is true, then the true block of statements will be executed.
