The Fibonacci numbers are the sequence of numbers F₁, F2, F3, ... where: • F₁ = F₂ = 1 ● F=F-1 + Fn-2 The Fibonacci numbers for n = 1, 2, ..., 8 are 1, 1, 2, 3, 5, 8, 13, 21. Use the function design recipe to develop a function named fib. The function header (with missing type annotations) is: fib(n). Parameter n is a positive integer. The function returns the n'th Fibonacci number. For example, fib (1) returns 1 and fib(6) returns 8. Your function must have exactly one loop. Your solution must Your function definition must have type annotations and a complete docstring. Use the Python shell to test fib.

Step by step
Solved in 3 steps with 2 images
- 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)C++ program Write a function named "reduce" that takes two positive integer arguments (as reference), call them "num" and "denom", treats them as the numerator and denominator of a fraction, and reduces the fraction.The function should return the value 0 (to indicate failure to reduce: if either of the two arguments is zero) and should return the value 1 otherwise.Function Prototype: bool reduce(int & num,int & denom);The statement in line1 is an example of int squareT (int x, int y) //line1 { if (x*C language is used Define a function called hypotenuse that calculates the length of the hypotenuse of a right triangle when the other two sides are given. Use this function in a program to determine the length of the hypotenuse for each of the following triangles. The function should take two arguments of type double and return the hypotenuse as a double.This is c programming question. Use function please for solving. Question: (The function that returns letter grade according to midterm and final grade) : The function turn_to_letter decides on the letter grade of the student according to the table below from the visa and final grades sent into it and returns it, write it together with a main function which the turn_to_letter function is called and prints the letter equivalent on the screen. - Success score = 40% of midterm + 60% of final, - F for the success score below 50, D for between 50 and 59, C for between 60 and 69, B for between 70 and 79, A for 80 and above.C++ The function prototype of a function that recieves two integer values and computes their sum and difference is given as follows: void computeSum (int num1, int num2, int & sum, int & diff); write the statments to call this function to compute and print the sum and the differnce of 167 and 84.Redesign this solution using functions. For this lab: You will define a function names main(). You will get input in the main function and pass it to the following functions: milesToKm() FahToCel() GalToLit() PoundsToKg() InchesToCm(). Each function will require that you have a local variable to store the result of the calculation. This result will then be displayed using the print statement from within the function. For this portion of the lab, you will reuse the program you wrote in Lab 5 Part1 A. Redesign this solution in the following manner: All of the functions used must now be value returning functions. Put the functions in an external module and let the main program import the module.Write a function called area circumference generator that takes a radius of a circle as a function parameter and calculates its circumference and area. Then returns these two results as a tuple and prints the results using tuple unpacking in the function call accorrding to the given format. [Must use tuple packing & unpacking] Example1: Function Call: area_circumference_generator(1) Output: (3.141592653589793, 6.283185307179586) Area of the circle is 3.141592653589793 and circumference is 6.283185307179586 ======== :===== Example2: Function Call: area_circumference_generator(1.5) Output: (7.0685834705770345, 9.42477796076938) Area of the circle is 7.0685834705770345 and circumference is 9.42477796076938C code blocks Write the complete function that receives a pointer to a single floating point number as an argument and returns that number after subtracting 100 from it. Define your function in the same way as the given function prototype. Take a look at the "For example" below to see how the function is used in the main function and the expected result. (For interest sake, note that this is a pass-by-reference function call.) #include <stdio.h>#include <stdlib.h>void subtractFunc(float *a);int main(){ float num = 357.900; subtractFunc(&num); printf("%.3f", num); return 0;} //Your answer starts here For example: Test Result float num = 357.900; subtractFunc(&num); printf("%.3f", num); 257.900Computer Science question Please write a program in Go Programming LanguageWrite a program to assign the value of b to a and value of a to b.you need to Create a function for the above descripted information and that will call from the main function.Also import the "fmt" In your programArgument type: - (string, string)Return type : - (string, string)call the Created function into the main functionPlease attach the output for the same in the solution.Solve only in the "GO Programming" Language.vUse 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…Write a function called area_circumference_generator that takes a radius of a circle as a function parameter and calculates its circumference and area.
