Declare double variables num1, den1, num2, and den2, and read each variable from input in that order. Find the difference of the fractions num1/den1 and num2/den2 and assign the result to fraction Difference. The calculation is: difference = num1 deni Ex: If the input is 1.5 3.5 4.0 4.5, the output is: -0.46 Note: Assume that den1 and den2 will not be 0. 5 int main() { 6 double fractionDifference; 7 double num1; 8 double den1; 9 double num2; 10 double den2; cin >> num1; 11 12 num2 den₂

The n'h Fibonacci Number can be calculated using the following formula: 1+ V5 :): V5 1 1 – V5. -)" –(- -)") Create a function with argument n where n is a nonnegative integer and returns the n'h Fibonacci Number. Note that the result won't be exact due to computer limitations of storing all decimal values. Use the round() function (e.g. round(12.4) results in 12 and round(12.5) results in 13) Note 1 Import math package inside the function and use math.sqrt() function. Note 2 There is no need to ask for input or print the output. Just submit the function with the following format: Соpy def fib(int1): # Your code here where int1) is a nonnegative integer. The function returns (1, 2, 5 when the arguments are (1, 3 and 5, respectively.

int x = 8, y = 3, z = 5; x += x + y * z + z * z; printf("%i\n", x); // what is the output
Example Output: Enter the number of rows: 8 1 1 1 1 2 1 13 3 1 1 4 6 4 1 15 10 10 5 1 16 15 20 15 6 1 17 21 35 35 21 7 1 (3.b): Use a “for loops" to print the invert of the above pascal triangle. The program should take the number of rows as input from the user. The output of the program should be as in the following pattern e.g., if you enter the number of rows = 8.
Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…
Read two numbers from user input. Then, print the sum of those numbers.Hint -- Copy/paste the following code, then just type code where the questions marks are to finish the code.num1 = int(input()) num2 = ? print(num1 + ?) Note: Our system automatically runs your program several times, trying different input values each time to ensure your program works for any values. Notes on how to solve this. This was my answer: num1 = int(input('5')) num2 = int(input('10')) print(num1 + num2) This was the issue: Testing with 5 + 10 Output differs. See highlights below. Your output 51015 Expected output 15 clearTest aborted

Use cin to read integer leftoverValue from input. Then, read the remaining integers from input until 99 is read. For each remaining integer read before 99, if the integer is positive, output the positive integer followed by a newline and subtract the positive integer from leftoverValue. Ex: If the input is: 57 -25 24 20 99 then the output is: 24 20 The total after subtracting all positive values is 13 Note: leftoverValue may go negative. 1 #include 2 using namespace std; 3 4 int main() { 5 6 7 8 9 10 11 12 13} int inputData; int leftoverValue; *Your code goes here */ cout << "The total after subtracting all positive values is " << leftoverValue << endl; return 0;
A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("After 6 hours: %.2f mg\n", yourValue); Ex: If the input is: 100 the output is: After 6 hours: 50.00 mg After 12 hours: 25.00 mg After 24 hours: 6.25 mg Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg. 1 import java.util.Scanner; 3 public class LabProgram { 06∞VOSAWNA 2 4 5 7 8 9 10 } PER 11 } 12 public static void main(String[] args) { Scanner scnr = new Scanner(System.in); double caffeineMg; // "double" supports floating-point Like 75.5, versus int for integers Like 75.

First, read in an input value for variable numVals. Then, read numVals integers from input and output each on the same line with ": " between each value. End with a newline. Note: ": " should not be at the beginning or end of the output. Ex: If the input is 4 -20 80 60 -10, then the output is: -20: 80: 60: -10 1 2 3 4 5 6 7 8 9 10 #include <iostream> using namespace std; int main() { intnumVals; /* Your code goes here */ return0; }
