- Instructions The program in the Programming Example: Fibonacci Number does not check: Whether the first number entered by the user is less than or equal to the second number and whether both the numbers are nonnegative. Whether the user entered a valid value for the position of the desired number in the Fibonacci sequence. Rewrite that program so that it checks for these things. NOTES: If an invalid number is entered for case 1 above, prompt the user to enter both numbers again. If an invalid number is entered for case 2, prompt the user to enter a value until a valid value is entered. the code: #include <iostream> using namespace std; int main() { //Declare variables int previous1; int previous2; int current; int counter; int nthFibonacci; cout << "Enter the first two Fibonacci numbers: "; //Step 1 cin >> previous1 >> previous2; //Step 2 cout << endl; //verify the first two values if(previous1<0 && previous2>0)…arrow_forwardThe code does not run accordingly # Main function def main(): # Initialize a local variable num=0 # Get a number from the user num=int(input("Enter an integer:")) # Call the function if is_prime(num): Why is the variable named num # Print the statement print(num,"is a prime number.") else: # Print the statement print(num,"is not a prime number.") # Function definition def is_prime(number): And here it is named number # Divide the number by 2 value=int(number/2) # Assign true to a variable status=True # Loop for i in range(2,value+1): # Check if number mod i is equal to 0 if number%i==0: # Assign false to a variable status=False # Return the variable return status # Call the main() function…arrow_forwardDomino's Time Function Name: dominosTime() Parameters: N/A Returns: None Description: During the summer, you ordered a lot of food from Domino's. Pizzas are $12, an order of pasta is $6, and chicken wings are $8. Write a function that asks the user how many of each food item they would like, and then print a response telling them what their order to- tal will be. The order total should be an integer. >>> dominosTime() How many pizzas do you want? 3 How many orders of pasta do you want? 2 How many orders of chicken wings do you want? 2 By ordering 3 pizzas, 2 orders of pasta, and 2 orders of chicken wings, your order total comes to $64.arrow_forward
- Task 2: Multiply of two fractions The formula to find the Multiply of two fractions is: 6a 4a+20 Multiply: 3a +15 2a² Write a program that ask user to enter (a) for the numerator and denominator of each fraction and displays the Multiply in fractional form.arrow_forwardPeriodic compounding The total accumulated value, including the principal sum P, is given by the formula: where: nt A = P(1 + 1) "² n A is the final amount Accumulated Value P is the original principal sum r is the nominal annual interest rate n is the compounding frequency t is the overall length of time the interest is applied (expressed using the same time units as r, usually years). Using the above formula write a program that will display the following table. Principal-Value | Times-Interest-Compunded | Annual-Int-Rate | Term | Accumulated-Value 1000 6.00% 10 3.20% 15 2000 3000 9.25% 10 2 ** 3 8 | You must use exponent operator to compute P Exponent Operator in Python is ** Examples m=3 n=2 p= m **n (https://en.wikipedia.org/wiki/Compound_interest) 1 2 4 base = 2 exp = 4 a = base ** exp print(a) 16 print("Solving the exponent, we get Solving the exponent, we get 9 ,p ) 1790.85 3219.89 7486.33arrow_forwardfloat variables are called single precision variables Select one: O True O False 17arrow_forward

The formula for this conversion is Celsius=5/9(Fahrenheit32).arrow_forward(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.arrow_forward
- (Numerical) Write an assignment statement to calculate the nth term in an arithmetic sequence. This is the formula for calculating the value, v, of the nth term: v=a+(n1)d a is the first number in the sequence. d is the difference between any two numbers in the sequence.arrow_forwardA structure that allows repeated execution of a block of statements is a(n) _____________. sequence selection array looparrow_forward4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward
