- In C++, Given the following function prototype: void testDefault(int a, int b = 7, char z = '*'); Indicate if each of the following function calls are valid or invalid a) testDefault(5); b) testDefault(); c) testDefault(6, '#'); d) testDefault(0, 0, '?');Assume that the declarations for two functions look as follows: int Function1(double x); 2.void Function2(double x); Give some sample code that would show how each function could be used.Give an example from your own idea, of a program that use a void function (does not return avalue), based on your understanding. (You must include a main function)
- For this question you will design and implement a function that takes 5 arguments and produces 5 return values. This question is internally recognized as variant 0371. The 5 arguments must be of types int, int, bool, bool, and char (in that order), and they must be stored in parameter variables 'ham', 'bar', 'xyz', 'gzk', and 'foo', respectively. As a clarifying example, the second parameter - 'bar' - will be of type int. The function you create must perform the operations list below, in the specified order and exactly as they are described here. You are NOT permitted to simplify the operations. 1. create a new variable named 'ukr' that stores the result of increasing the 'ham' parameter by 42 2. if the conjunction of the 'xyz' parameter and the 'gzk' parameter has a value of True, multiply the value of the 'ham' parameter by a value of 29 and store the result back in 'ham' 3. negate the value of the 'xyz' parameter and store the result back in 'xyz' 4. decrease the value of the 'ham'…Write a declaration for a function called test( ) that takes 2 arguments and returns type char. The first argument is type int and the second is type float with a default value of 5Consider the following function call: draw_circle('red', 3) What is the function name and what is the first argument passed to the function? a. The function name is draw_circle and the first argument is 3. b. You need to see the function definition to determine the function name and arguments. c. The function name is draw_circle, but you need to see the function definition to determine the arguments. d. The function name is draw_circle and the first argument is 'red'. e. The first argument is 'red', but you need to see the function definition to determine the function name.
- 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 myInt and float myFloat whose values are 20 and 4.8, respectively. What are the values of myInt and myFloat after return from the following function call? Demo(myInt, myFloat); myInt: myFloat: b. Also, describe what happens in MEMORY when the Demo function is called. Think about the by reference and by value parameters.17. A function should determine the average of x and y. What should be the function's parameters and return value(s)? A.Parameters: none Return values: X,y B.Parameters: ×, y, average Return value: none C.Parameters: average Return values; X, y D.Parameters: X, y Return value: average1. Write a program in python that contains a main function and a custom, void function named show_larger that takes two random integers as parameters. This function should display which integer is larger and by how much. The difference must be expressed as a positive number if the random integers differ. If the random integers are the same, show_larger should handle that, too. See example outputs. In the main function, generate two random integers both in the range from 1 to 5 inclusive, and call show_larger with the integers as arguments.EXAMPLE OUTPUT 13 is larger than 1 by 2EXAMPLE OUTPUT 2The integers are equal, both are 3
- 2. If a function have all the default arguments but still some values are passed to the function then _________.This is python Regarding a function, which of the following is not true? The def keyword is used to create a function. A function must contain a return statement. When a function is defined, it must have parentheses. A function can contain another function.Engineers often measure the ratio of two power measurements in decibels, or dB, which can be calculated as follows:dB= log10P2/P1Where P2 is the power level being measured, and P1 is some reference power level. Write a function that calculates the level. The function’s prototype is as follows:double dBCalculator (double P1, double P2);Then, call dBCalculator from the main function to find the power ratio for the measurements from 1 to 20 Watts, in 2 Watt steps. You can assume that the reference power P1 is 1 Watt.
