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)3. Write a function which will swap its arguments if the first argument is greater than its second argument, but will not interchange them if the first argument is smaller than or equal to the second argument. The function should return 1 if a swap was made, and 0 otherwise. (Hint: Make sure to use call by reference.) Write also a short test driver(i.e. a main() invoking your function).Given person_is_old(age) which returns True or False based on the incoming age as an integer. Write a function that uses the one mentioned above so that it prints “Go to work!” if the person is not old and “You deserved to have a long vacation” otherwise. Your function must also accept the age as its argument. My code def funct2(age): flag = old_person(age) if(flag): print("You deserved to have a long vacation") else: print("Go to work!")
- 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) + 5def truth_value(integer): """Convert an integer into a truth value.""" # Convert 0 into False and all other integers, # including 1, into True if integer == 0: truth_value = False else: truth_value = True return truth_value Now, write a function that goes in the opposite direction of the truth_value() function. This new function should convert a truth value into an integer. In particular, True should be converted into 1 and False into 0. Name the new function integer_0_or_1(). All you need to include below is your definition of the function integer_0_or_1(). It will be tested automatically against relevant inputs. So include your function and nothing more.Use C++ to write this code Write a function called tuneSimilarity that computes the similarity score as described above for two tunes of equal length. Function Specifications: Name: tuneSimilarity() Parameters (Your function should accept these parameters IN THIS ORDER): tune1 (string): The first input tune tune2 (string): The second input tune Return Value: The similarity score (double) The parameters should be two strings of equal length. If they are not equal in length, your function should return 0. The function should not print anything. You may assume that the input to tuneSimilarity will always be valid SPN, i.e. you do not have to account for arbitrary strings. --- Examples --- Sample function call Expected return value tuneSimilarity("G4E5D4", "G4F4D5") 0.666667 tuneSimilarity("A0B0C0D0", "D1C1B1A1") -4 tuneSimilarity("E5E5G5A6G5D5", "E5G5A6G5D5D5") 0.333333 tuneSimilarity("D5G2", "F7D1E4G4") 0 An example test case for the first sample function call would…
- 1. 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 3Write a function named midvalue that is passed three unique int values and returns the one that is in the middle. Thus, midvalue(5,28,14) returns 14. C++Write a function argument_count that accepts an integer i, followed by any number of additional arguments. The function should returnTrue if the value given to i is equal to the number of arguments that follows it, and should return False otherwise.
- QUESTION 22 Write ONLY the function to do the following: Input a number selected by the user That number MUST be between 10 and 15 The upper and lower range of the answer must be passed as arguments to the function If the number is NOT in the right range, the user MUST be prompted to input the right answer again Return the answer to the calling function when correctWrite a function NewCalculateGrade that takes a double score and uses reference parameter to return the grade and call this new function from main. You can use #include<iostream>using namespace std; char CalculateGrade(double); int main(){double score;cout << "Grade is "<< CalculateGrade(87); } char CalculateGrade(double score){char grade;if (score >90)grade ='A';else if (score >80)grade ='B';else if (score >70)grade ='C';else if (score >60)grade ='D';elsegrade ='F';return grade;}Write two or more function, parameters and arguments that generates a random license plate. Your function should have approximately equal odds of generating a sequence of characters for an old license plate or a new license plate. Write a main program that calls your function and displays the randomly generated license plate.
