Arduino Functions Syntax

What is the syntax for declaring a function in Arduino?

• returnType functionName(parameters) { // code to be executed }

• returnType functionName(parameters) // code to be executed

• functionName(parameters) // code to be executed

• functionName(parameters) { // code to be executed }

How do you call a function in Arduino?

• Define the function but never call it

• Declare the function and then call it using a different name

• Call the function without defining it first

• Declare the function prototype and define the function in the code, then call the function by using its name followed by parentheses.

What is the syntax for specifying the return type of a function in Arduino?

• functionName returnType(parameters)

• returnType functionName(parameters)

• parameters functionName(returnType)

• functionName(parameters) returnType

How are parameters defined in a function in Arduino?

• Parameters in a function in Arduino are defined using curly braces

• Parameters in a function in Arduino are defined outside the function body

• Parameters in a function in Arduino are defined within the parentheses following the function name. Each parameter is separated by a comma and consists of a data type followed by the parameter name.

• Parameters in a function in Arduino are defined after the function name

What is the syntax for defining a void function in Arduino?

• void functionName()

• void functionName() {}

• void functionName()

• void functionName()

In Arduino, how do you declare a function that takes an integer parameter?

• void functionName(int parameter)

• int functionName(int parameterName)

• void functionName(int parameterName)

• void functionName(integer parameterName)

What is the correct way to call a function with parameters in Arduino?

• myFunction(value1 value2);

• myFunction(value1, value2,);

• myFunction(value1, value2);

• myFunction(value1, value2)

• myFunction(value1, value2);

How do you define a function that returns a float value in Arduino?

• Define the function as 'boolean'.

• Specify the return type of the function as 'float'.

• Declare the function as 'void'.

• Use 'int' as the return type.

What is the purpose of a void function in Arduino?

• To print a message on the serial monitor

• To perform actions without returning a value

• To return a value without performing any actions

• To stop the execution of the program

Explain the syntax for passing multiple parameters to a function in Arduino.

• functionName(param1, param2, param3)

• void functionName(int param1, float param2, String param3)

• void functionName(param1, param2, param3)

• void functionName(int param1, int param2, int param3)
