Question
Chapter 4.6, Problem 26STE
Program Plan Intro
Description of Function:
Function has two parts that are called “function declaration” and “function definition”.
- The function declaration defines how the function is called.
- The function definition defines how the function computes the value it returns.
Parameters and arguments:
The parameter is used to denote to the variable as found in the definition of function and it is also called formal parameters.
The argument denotes to the actual input provided at function call and it is also called actual parameter.

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.arrow_forward3. Write a function which will swap its arguments if the first argument is greater than its second argument, but will not interchange them if the first argument is smaller than or equal to the second argument. The function should return 1 if a swap was made, and 0 otherwise. (Hint: Make sure to use call by reference.) Write also a short test driver(i.e. a main() invoking your function).arrow_forward
- 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.)arrow_forwardIn C++ Language (please use hint) : Write a function which will swap its arguments if the first argument is greater than its second argument, but will not interchange them if the first argument is samller than or equal to the second argument.

Each stub must also contain the function's parameters.

- Explain why it's okay for a function to have side effects on occasion.arrow_forwardWhat is the difference between a formal parameter and an argument? Group of answer choices A function’s argument is referred to as the formal argument to distinguish it from the value that is passed in during the function call. The parameter is the passed value. A function’s parameter is referred to as the formal parameter to distinguish it from the value that is passed in during the function call. The argument is the passed value. A function’s parameter is used for passing by reference. The argument is used for passing by value. A function’s parameter is used for passing by value. The argument is used for passing by reference. They are identical but using different terms.arrow_forwardExplain the purpose of a function parameter. What’s the difference between a parameterand an argument?arrow_forward
