Concept explainers

Types of Function

A function is a process or task that does some operation in the program. Some programming languages may contain built-in functions for certain commonly used tasks. Most programming languages also support user-defined functions, which means a user can write their own function to perform some operation. There are some libraries or header files that contain built-in functions for performing certain tasks.

Question

To determine whether a variable is being passed to a function by value or by reference, you will need to examine_________ .
a. the statement that invoked the function
b. the function header
c. the statements entered in the function
d. either a or b

Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)
What are supplied to a function when it is called?_______
_______ are variables available only within the body of a declared function. A. Arguments B. Globals C. Parameters D. Locals
c++ If you pass a variable by ________________ to a function, the function will have access to the parameter’s original argument. Changes to the parameter are also made to the argument.
Write a function, named timesTen, that accepts an integer argument. When the function is called, it should display the product of its argument multiplied times 10.
What are supplied to a function when it is called? _____ arguments numbers return values sentinals
C++ If you pass a variable by ________________ to a function, the function will make a local copy of that variable and use that copy throughout the function’s execution. Changes to the parameter are not made to the argument.
Create a function that will calculate the area of a circle using the radius. The user should enter the radius in the main and send it into a CircleArea() function that you create. The function should return the area variable into the main. Print the area in the main
_________ arguments are passed to parameters automatically if no argument is provided in the function call.
Fill-in-the-Blank Special variables that hold copies of function arguments are called _________.
Related to R code. Question: Write a function called temp_categorizer that takes one argument ‘temperature’ and returns the following: - a value of “hot” if temperature is greater or equal to 90 - a value of "warm" if temperature is greater than 60 but less than 90 - a value of "cold" if temperature is more than 32 but less than 60 - a value of "freezing" if temperature is 32 or below And also Use the following vector for problem number : sentence <- c("Learning", "loops", "in", "R", "is", "not", "that", "bad") Create a loop that: loops over the range of possible word lengths displays a message detailing the words that match the length For example: at length 8, the loop should state that the word "Learning" has 8 letters Hints: Use the function nchar() which gives the number of letters in each word. • Example: try nchar(sentence) min() and max() may help you specify a range
# Exercise 8: Create a function that takes the sum of three numbers and returns the value # Make sure to use the function and display the result # When you are done, get 3 numbers from a user and then print out the sum using your function
