Write and test the “digit” function:Function Prototype: int digit(int n,int k)This function returns the kth digit of the positive integer n. For example, if n is the integer 29,415, then the call digit(n,0) would return the digit 2, and the call digit(n,2) would return the digit 4.
1. Consider the function definition:
void Demo (int intVal, float& floatVal
{
intVal = intVal * 2;
floatVal = float(intVal) + 3.5;
}
a. Suppose that the caller has variables int mylnt and float myEloat whose values
are 20 and 4.8, respectively. What are the values of mylnt and myEloat after
return from the following function call?
Demo(mylnt, myEloat);
mulnt:
mvEloat:
b. Also, describe what happens in MEMORY when the Demo function is called.
Think about the by reference and by value parameters.
Write a function named check() that has three parameters. The first parameter should accept an integer number, and the second and third parameters should accept a double precision number. The function body should just display the values of data passed to the function when it’s called.(Note: When tracing errors in functions, having the function display values it has been passed is helpful. Quite often, the error isn’t in what the function body does with data, but in the data received and stored.)

Group of answer choices An argument is a variable that is created in a function to hold a value that has been sent to it and a parameter value is the value that a function returns to the calling routine. An argument is a value that is passed into a function and a parameter is variable that the function defines to hold value of the argument. An argument is a value that is passed into a function and a parameter is the value that a function returns to the calling routine. A parameter is a value that is passed into a function and an argument is the value that a function returns to the calling routine.arrow_forward
