What does return in void mean
A void function can return
It indicates that the function is terminated. It increases the readability of code.
Does void mean no return
In computer programming, when void is used as a function return type, it indicates that the function does not return a value. When void appears in a pointer declaration, it specifies that the pointer is universal.
What is return type or void
The void type, in several programming languages derived from C and Algol68, is the return type of a function that returns normally, but does not provide a result value to its caller. Usually such functions are called for their side effects, such as performing some task or writing to their output parameters.
How does a void function return
A function that does not return a value is called a non-value returning function (or a void function). A void function will automatically return to the caller at the end of the function. No return statement is required.
Should I use return in void
ANSWER. C51 does not require a return statement for void functions. The best example of this is the main C function. Nonetheless, it is a good idea to insert a return statement anyway.
What happens if you return in a void function
In lieu of a data type, void functions use the keyword "void." A void function performs a task, and then control returns back to the caller–but, it does not return a value. You may or may not use the return statement, as there is no return value.
Is void a refund
Unlike a void where you essentially cancel the sale, a refund is processing a second, offsetting sale. So, your customer will FIRST get debited the original sale amount, then later, AFTER the refund processes, they'll see an equivalent credit in their account. This delay can sometimes be frustrating for customers.
What happens when you void a refund
Refunding a transaction returns money back to a customer's credit card; it takes three to five business days for the transfer to complete. A void transaction cancels the original transaction as if it never happened and needs one to 3 business days to take effect.
What are examples of return types
Return Types
| Name | Return Type | Description |
|---|---|---|
| AVG | Double | Returns the mean average of the fields |
| COUNT | Long | Returns the total number of results |
| MAX | The type of the field | Returns the highest value in the result set |
| MIN | The type of the field | Returns the lowest value in the result set |
What is an example void function
Void functions are mostly used in two classes of functions. The first is a function that prints information for the user to read. For example (for our purposes), the printf function is treated as a void function.
What is void and non-void function
Answer: Void functions are those functions that do not return any value or don't have a return statement. Non-void functions always return a value.
What is an example of a void method
Examples of void methods include output methods such as: outputInt, outputDouble, outputString, outputlnInt, etc. Such void methods stand alone, and end with a semicolon; they are not parts of other expressions.
What is the difference between void and return value
The main difference between the two types of methods is the type of value that is returned. Void methods do not return a value, while value returning methods return a value of a certain type. A void method may be necessary in scenarios where an action needs to be performed without returning a value.

What does void payment mean
An unsettled transaction can be voided which stops the transaction from processing and removes it from the customer's account, effectively canceling the transaction. Once a transaction has been settled, it can only be refunded. A partial refund can only be made to a settled transaction.
How long does it take for void to refund
Once voided, the transaction should disappear from the customer's bank statement within 24 hours. Processing times may also vary depending on your bank or credit card company, but generally a void should never take more than four business days.
Is refund and void the same
Unlike a void where you essentially cancel the sale, a refund is processing a second, offsetting sale. So, your customer will FIRST get debited the original sale amount, then later, AFTER the refund processes, they'll see an equivalent credit in their account. This delay can sometimes be frustrating for customers.
What are the 3 types of return

What are the 4 types of returns
Let's understand the different types of returns in mutual funds and their significance:Absolute Returns:Annualized Returns:Total Returns:Point to Point Returns:Trailing Returns:Rolling Returns:
What is void in main function
A void keyword is used to reference an empty data type. We can use the void keyword as the return type of the main function in c to depict that the function is not returning any value. Let us first see the syntax and then the example of this prototype.
What is void vs non void function
The way that a non-void method is called differs from the way that a void method is called in that the call is made from within other Java statements. Since a non-void method always returns a value, this value has to be stored in a variable, printed, or returned to a Java control structure or another method.
What is the difference between void and return function
Void functions are created and used just like value-returning functions except they do not return a value after the function executes. In lieu of a data type, void functions use the keyword "void." A void function performs a task, and then control returns back to the caller–but, it does not return a value.
What does void method mean
should not have a return value
The void keyword specifies that a method should not have a return value.
Why do we use void example
When used as a function return type, the void keyword specifies that the function doesn't return a value. When used for a function's parameter list, void specifies that the function takes no parameters. When used in the declaration of a pointer, void specifies that the pointer is "universal."
What means void value
void (C++)
When used as a function return type, the void keyword specifies that the function doesn't return a value. When used for a function's parameter list, void specifies that the function takes no parameters. When used in the declaration of a pointer, void specifies that the pointer is "universal."
