Step by step
Solved in 2 steps
- 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)The parameters passed to function are .called formal parameters True O Fales OA(n) is a variable that is used within a function. Select one: a.operator b.property C.parameter d.method
- A variable x is assigned a NULL value. The return value from the function is.null(x) will be a. TRUE b. "Number" c. NULL d. "Character"True/False 3. Information can be passed into a function through parameters.To make a function return more than one result we pass parameters: By value. As int. By void. By reference.
- Detect Even/Odd Write a function with no parameters, even_or_odd() in Python Specifications: read an integer from standard input return 0 if the integer is even, 1 if the integer is odd do not use a conditional ("if") statement, just use modular arithmetic (such as // or %) do not print the result, return it HINT: What is the remainder when you divide an even number by 2? What is the remainder when you divide an odd number by 2? REMINDER: DO NOT use prompts in your input statements for this problem. For example: Test Input Result ans = even_or_odd() print(ans) 5 1 ans = even_or_odd() print(ans) -14 0 ans = even_or_odd() print(ans) 0 0 ans = even_or_odd() print(ans) 99 1The parameters received by function are .called actual parameters True O False O nTRUE OR FALSE Variables declared inside the function are local to that function.
- Convert radians into degrees Write a function in Python that accepts one numeric parameter. This parameter will be the measure of an angle in radians. The function should convert the radians into degrees and then return that value.1- Write a python function that takes a number as a parameter and returns true if the number entered by the user is a integer and returns false otherwise.python module must define four functions:a. add(a, b)b. subtract(a, b)c. multiply(a, b)d. divide(a, b)i. Divide must check for division by zero and return an error message if itencounters it.3. Each function should take two arguments and perform the corresponding mathematicaloperation. Return the result, don’t print it in the function.4. Include a main() function that tests these functions with some example inputs. Ensurethat you print the results of the function calls here in the main function and provide theappropriate labels.5. The main() function must only run automatically if the module is being run directly, notwhen imported.
