- 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)(Numerical) Heron’s formula for the area, A, of a triangle with sides of length a, b, and c is A=s(sa)(sb)(sc) where s=(a+b+c)2 Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of sand[s(sa)(sb)(sc)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A=1. The value of A should be returned by the function.Which statement below is true about a function: may have no parameters must always have a return statement must have at least one parameter its arguments always appear within brackets
- Question 11 mahTrue or false: 1. A parameter MUST be a variable. 2. There can never be any quotes in the parameter list of the function. 3. Parameters get their values from the function call. 4. You can send the same function different values using the parameters, every time you call the function.

- Calling a function and defining a function mean the same thing True or FalseWhich statement of the following is the most appropriate? Group of answer choices One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. These form a contract between the programmer who uses the function and the programmer who writes the function. Using the assert function to check preconditions can significantly reduce debugging time, and the assertion-checking can later be turned off if program speed is a consideration.

- At most one paragraph, describe a scenario that will require the use of multiple functions and parameters for an application. Your assignment should require at least: One function that returns a value One function that does not return a value One or more parameters Then, solve your own problem. The solution should include: an IPO chart to describe the solution a function table that includes a row for EACH function flowcharts for each function in the table and, a complete Python program that implements your solution.Change this question to 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.
