1. define a function with one parameter and no return value. Add code to print out the value of the parameter. Write a line of code to call your function 2. define a function with two parameters where one of them has a default value of zero - you should be able to work out which of the parameters this can be. The function should return a value equal to the first parameter minus the second parameter. Write a line of code to call your function 3. define a function that takes one parameter that is assumed to be a tuple with 2 elements. The function should return a tuple where the order of the two elements is switched. Write a line of code to call your function.

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 is the difference between a function argument and a function parameter? 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.
8. Write a function with one parameter. The function should accept the value of a radius as its argument and return the volume of the sphere with that radius. Note that the radius may be a decimal fraction. The function should not read or print anything.
The Issue: You have a function that accepts a variety of parameters. It is impractical to provide them as traditional parameters. So, what are you going to do?
What 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.
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.)
3.Inside a function with two parameters, print the first parameter. * def my_function(firstName, lastName): print (
5. Write a function that returns the factorial of the number sent to it as a parameter. The parameter and the number returned will be of type double. 6. Write to it a function named fnk, which returns a variable of type double (using the Math.Sin function to use a radian value as the parameter of this function). x '+ x * sin (x) + 5
Explain the purpose of a function parameter. What’s the difference between a parameterand an argument?

Change each one of these questions to now work using a function. decide what the name of the function of each should be, how many parameters are required and what value needs to be returned. You’re no longer required to solve the problem - try to re-manage your code to be a function. Write a program that uses input to prompt a user for their name and then welcomes them. Enter your name: Chuck Hello Chuck
Write function headers for the following:a. 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 returns no value.b. A function named findAbs() that accepts a double-precision number passed to it and returns its absolute value.c. A function named mult() that accepts two floating-point numbers as parameters, multiplies these two numbers, and returns the result.d. A function that produces a table of the numbers from 1 to 10, their squares, and their cubes. No arguments are to be passed to the function, and the function returns no value.e. Write a function named rightTriangle() that accepts the lengths of two sides of a right triangle as the arguments a and b. The function should determine and return the hypotenuse, c, of the triangle.
