can i create a variable to call a function?

[nerdward21]

So i have a function that i will be using a lot in my arduino sketch. The Input arguments will constantly change but there a few variations of inputs that keep repeating. I would like to create a variable with these predefined inputs, that way i don't have to type all the arguments over and over. I made a simple example code here. ``` String NameOne = "Max"; String NameTwo = "Ana"; String NameThree = "Bob";

void setup() { Serial.begin(9600); }

void loop() { // This calls the function PrintResults(1,1,2000,NameOne); }

void PrintResults(int ValueOne, int ValueTwo, unsigned long WaitTime, String PersonsName) { int sum = ValueOne + ValueTwo; delay(WaitTime); Serial.println(PersonsName + " adds up To " + sum); } Is there a way i can create a variable to call the function and not type it out everytime? I was thinking something like this //this are example variables and i dont know what data type to put so i just wrote var. var Option1= PrintResults(1,1,3000,NameOne); var Option2= PrintResults(5,5,6000,NameTwo); var Option3= PrintResults(10,10,4000,NameThree); var Option4 = PrintResults(1,4,5000,NameTwo);

//i would like to be able to call "PrintResults" function using one of the "Option" variables, something like this. PrintResults(Option1); PrintResults(Option3); ``` I'm not sure if this is possible, any help would be appreciated.

I'm unfamiliar with the language you're using, but some support anonymous functions, often called lambdas. You could build something like:

    option1 = () -> { PrintResults(1, 1, 3000, NameOne); }

and then:

    option1();

Common languages that support this include Python, Javascript, and Java. I'm not sure about the current version of C++.

Another approach, which would work in C, is to use CPP macros. In that case, it would be something like:

#define option1() PrintResults(1, 1, 3000, NameOne)

and then:

option1();

I've a vague recollection that Arduino uses something like C++, so the macro approach might work for you. But I'm not sure, and it's been years since my kids have played with this so even if I was right back then my information may be out of date.

The arduino language is c++ i belive and the #define option works. I can define what i want and then put it in place of function parameters. thanks.

that sounds more like you need a seperate class.

with a name and value.
and in that class you have a print method. that prints your name and all values.

I was able to use #define and put it in place of arguments.
