In PyCharm, write a program that prompts the user for their name and age. Your program should then tell the user the year they were born. Here is a sample execution of the program with the user input in bold:
What is your name? Amanda How old are you? 15 Hello Amanda! You were born in 2005.
Hello Amanda! You were born in 2005.
Write the program. Format your code using best practices. Refer to the zyBooks style guide, if needed, to use proper naming conventions for variables and methods. Use the most appropriate statements with minimal extraneous elements, steps, or procedures.
Run the program.
Debug the program. Be sure your code produces the correct results.
Save and submit your file.
Copy the code provided and paste the code into the code window. The following code reads in a value for variable numApples using cin >> and outputs the value of numApples, followed by " apples" using cout <<.
cin >> numApples;
cout << numApples << " apples" << endl;
#include <iostream>using namespace std;
int main() { int numApples; // Creates an integer variable named numApples
/* Your code goes here */
return 0;}
A first year level 100 first semester student wrote the code below but could not tell whether it will execute or not. Assuming you are in a group discussion and the issue came up, determine giving reasons why it will or will not run. How else will you initialize the variables and explain your answer? struct ShattaWale { int brukutu = 0; dourble AlomoBitters = 0; };

- In Chapter 4, you created a program that generates a random number, allows a user to guess it, and displays a message indicating whether the guess is too low, too high, or correct. Now, create a modified program called GuessingGame2 in which the user can continue to enter values until the correct guess is made. After the user guesses correctly, display the number of guesses made. Recall that you can generate a random number whose value is at least min and less than max using the following statements: Random ranNumber = new Random(); int randomNumber; randomNumber = ranNumber.Next(min, max);arrow_forwardAssume that you have declared a variable as double hourly = 13.00;.What will the statement WriteLine(hourly); display? a. 13 b. 13.0 c. 13.00 d. 13.000000arrow_forwardWhat is the output of the following code segment?inte=5,f=10;if(eff0) Write(Red); else Write(Orange); a.

- The temperature of an object changes when it absorbs or loses thermal energy. It is possible to relate the amount of heat transferred, denoted by a variable q with units of joules, to the quantity of the substance m, by the following equation: q = mCsΔt Write a script that calculates amount of heat transferred for any amount of aluminum. Aluminum has a specific heat Cs = 0.897. The program should prompt the user to enter values for Δt and m, and should return the amount of heat transferred in units of joules. Test the program with values of 20 ℃ and 100 g.arrow_forwardWrite an application that asks a user to enter an integer. Display a statement that indicates whether the integer is even or odd.arrow_forwardNeed help to create the question below. Write a sub called GetName that asks the user to type a first name and last name in an input box, which is captured in a variable fullName. It should then call a sub called ProperCase that takes a single argument, a string, and converts this argument to proper case. For example, if the user enters the name gEORge cLOONey, the sub should return George Clooney. The GetName sub should then display the result, suhc as Geogre Clooney in a message box. Write a function called NextCell that takes a string as argument, (i.e., Address of the cell,) which should look like the address of a cell such as C2. The function should return True or False depending on whether the cell to the right of this one contains a formula. For example, if you pass C2, it checks whether D2 contains a formula.arrow_forward
