Complete the code that returns the value of f(x), which has the value 1 inside the range −1 ≤ x ≤ 1 otherwise it is the value 0. f(x) [ ] # complete the function to return the value of 1, x = [-1, 1] 0, otherwise #f(x) given x. # return as the value called variable def function_f(x): # YOUR CODE HERE return fval "fval" ## Check your code below using print command ← → +0 0+
def 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.

Modify the code you had previously so that the function print_bill outputs the actual names of the movies and categories, as opposed to just the numbers. You should also ask the user to enter their full name and phone number, which will also be included in the final bill. The output format is shown below. Billed to: FirstName LastName Phone Number: +212 6 00 00 00 00 Items Purchased Category Item Price Name of category 1 Name of item 1 cost 1 Name of category 2 Name of item 2 cost 2 Total: Sum of item prices (Before tax) Final Cost: Cost Including Tax and Discount.
What is the return value of the given function below when the data passed to it is 4? int function(int x) { int y; } y=x++; return y; Select one: O a. 6 O b. 7 O c. 5 O d. 4
4. You are given the following functions: int functionA(int a) { printf ("a-sd\n", a); if (a==1) return 1; else return functionB (a-1) *2; int functionB (int b) { printf ("b=3d\n",b); if (b--1) return 1; else return functionA (b-1) *3; Write the main function. Your main function should prompt the user for input and then call the mutual recursion by passing in the user's input. The guidelines are described below. int main () { //declare int a to receive user input and int result to receive result of mutual recursion //using a while loop, prompt user for input. The number entered //must be bigger than 1, otherwise repeat user input with an error //message. //call functionA () with int a as input argument. Receive the result in int result. //print result return 0;
6. You are given the following function that will calculate the sum of the first n numbers where n is an argument to the function. When n is 10, it should print out 55, but instead it prints out 10. Find and fix the problem. int findsum (int n) { int sum = 0; for (int i=1; i
