Outputs do not matter when it comes to functions, the definition is that any input can have at most one output (it is possible for an input to zero or one outputs). Thus, the first statement is true because it does not matter about outputs, but the second is false because you need a one on one relationship between input and output.
What gives exactly one output for every input?
- Since words may have more than one definition, “relating words to their definition in a dictionary” is not a function.
- Since for any given time, objects cannot be “two places at once,” this is a function.
- Since every person only has one birth date, “relating people to their birth date” is a function.
Can a device be used for both input and output?
Use of both input and output devices:- It really depends upon your point of view. For example, if you connect a temperature sensor to a laptop, then its an input device. For example, if you connect a temperature sensor to a laptop, then its an input device.
Can the work output ever equal to the input?
The output work can't be greater than the input work because of the friction that occurs. The input work is divided by the output work and "losses" due to friction Can a simple machine's efficiency ever be greater than 100%
Can a function have more than one input?
function. close window. A function is any relationship between inputs and outputs in which each input leads to exactly one output. It is possible for a function to have more than one input that yields the same output. function machine. Output
Can you have multiple outputs?
It is important to note that when one says multiple outputs, it is not that there are several alternative outputs, there is a set or ordered sequence of outputs. You can view the output as a single sequence or as several numbers. When you talk of multiple outputs you are viewing it as several numbers.
Why can't a function have 2 outputs?
No; functions are relations between an input and a single output. It is like a machine where something goes in, and then only one thing comes out, and it only depends on the input. That is . A relation between two sets is a collection of ordered pairs and we use the notation to mean that .
Can a function have multiple inputs?
Short answer: Yes. Long answer: Yes, but using the Cartesian product, you can consider multiple inputs as being a single input, where the single input is an ordered pair.
How many outputs are there for each input in a function?
one outputA function is a relation between sets where for each input, there is exactly one output.
How to return multiple values in Python?
That said, there are many ways in which you can return multiple values, using non-atomic return values. Depending on your programming language, you can use tuples, arrays, or other structured types. For example, in Python: 1 def fn (x): 2 return (x+1, x*3)
What is function in programming?
A function is essentially something that processes the inputs, to give a single output- be it math or programming. However, if you want to give more than one output, one easy way is to use an array. , Programming since punch cards were used to write code.
Can the producer and consumer synchronize?
In either of these cases the producer and the consumer cannot synchronize. One cannot wait for the other. Instead, the buffer is set up as a sampling buffer. The producer writes data whenever it has data to write. The consumer reads data from the buffer in a non-destructive manner whenever it needs data to process.
Do functions have input?
But in general, the answer is no. Functions do not necessarily have any input (from keyboard) or output (to screen) at all. A “Function” is just a block of source code that you can call at-will. As for what it does, it can do anything you want, or nothing at all.
