Programming & Computer Science Answers

Write a C++ program that performs the four arithmetic operations (addition, subtraction, multiplication and division) on two numbers received from keyboard by prompting. Your program must have specific function for each arithmetic operation. 

Create a class named Fruit with a data member to calculate the number of fruits in a basket. Create two other class named Apples and Mangoes derived from class Fruit to calculate the number of apples and mangoes in the basket. Print the number of fruits of each type and the total number of fruits in the basket. 

Write a program to count the palindromic array elements from the group of 30 array elements where array is allocated memory dynamically.

Get an integer from the user and check if it is divisible by 2. Print appropriate message on the screen

Declare two variables a and b to store values 2.1 and 6.4. Declare another variable c and assign it the result of a * b.

Use a for loop and the list append method to generate the powers of 2 to produce the following result [1, 2, 4, 8, 16, 32, 64, 128]

Write a for loop that prints a dictionary's items in sorted (ascending) order

a. Write a for loop that prints the ASCII code of each character in a string named S. Use the built-in function ord(character) to convert each character to an ASCII integer.

b. Next, change your loop to compute the sum of the ASCII codes of all characters in a string

At the interactive prompt, define a list named L that contains four strings or numbers (e.g., L=[0,1,2,3]). a. What happens when you try to index out of bounds (e.g., L[4])?

b. What about slicing out of bounds (e.g., L[-1000:100])?

c. Finally, how does Python handle it if you try to extract a sequence in reverse—with the lower bound greater than the higher bound (e.g., L[3:1])? Hint: try assigning to this slice(L[3:1]=[‘?’]) and see where the value is put
