Python 3.7.4 Given that add, a function that expects two int parameters and returns their sum, and given that two variables, euro_sales and asia_sales, have already been defined: Write a statement that calls add to compute the sum of euro_sales and asia_sales and that associates this value with a variable named eurasia_sales.
1(a): Implement the following C function : concatenate the lowest byte of each of two integers. The output should have 0's in the two most significant bytes , followed by the least significant byte of the first then second argument . For example , concatLowBytes (0x12345678 , 0xaabbccdd) 0x000078dd . You may use hexidecimal constants of any size. You should not use binary notation , function calls , loops or conditional statements. Examples : concatLowBytes ( 0x00000011 , 0x00000022)=0x00001122 concatLowBytes (0x12345678 , 0xaabbccdd )= 0x000078dd int concatLowBytes (int x, int y){ }
5.28 LAB: Convert to binary - functions Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110 Your program must define and call the following two functions. The IntegerToReverseBinary() function should return a string of 1's and 0's representing the integer in binary (in reverse). The ReverseString() function should return a string representing the input string in reverse. string IntegerToReverseBinary(int integerValue)string ReverseString(string userString)
5.21 In Python: A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is: 1712 the output is: 1712 is a leap year. Ex: If the input is: 1913 the output is: 1913 is not a leap year. Your program must define and call the following function. The function should return true if the input year is a leap year and false otherwise.def is_leap_year(user_year)
10.25 LAB: Quadratic formula Implement the quadratic_formula() function. The function takes 3 arguments, a, b, and c, and computes the two results of the quadratic formula: x1=−b+b2−4ac2a x2=−b−b2−4ac2a The quadratic_formula() function returns the tuple (x1, x2). Ex: When a = 1, b = -5, and c = 6, quadratic_formula() returns (3, 2). Code provided in main.py reads a single input line containing values for a, b, and c, separated by spaces. Each input is converted to a float and passed to the quadratic_formula() function. Ex: If the input is: 2 -3 -77 the output is: Solutions to 2x^2 + -3x + -77 = 0 x1 = 7 x2 = -5.50

Define a function named int to reverse_binary() that takes an integer as a parameter and returns a string of 1's and O's representing the integer in binary (in reverse).

7. using c++, If c is a character (e.g. char c = ‘a’), then (int) c is a number between 0 and 255 that represents its ascii value of that character (the ascii value of ‘a’ is 97.

Write a function that accepts two characters, c1, and c2, determines whether (int) c1 is greater than (int) c2, and then returns the sum of the ascii values of all the characters between c1 and c2.

Part 2: Binary Arithmetic One of the most common operations we perform on binary numbers (and all numbers) is addition. It can be cumbersome to convert your binary numbers to decimal just to add them and convert them back, so instead we will be learning how to add binary numbers directly. Binary addition works the same way as decimal addition, with the added restriction that each digit can only go up to 1. Let's consider the possibilities for adding the values of any 2 single digits together: 0 + 0 0 + 1 1 + 0 1 + 1 0 1 1 10 (remember that 10 in binary represents the number 2) In that last case, the result is larger than a single digit. When adding larger binary numbers, that means we have to carry the 1 over to the next column. This presents us with another new case: what happens if we have 1 + 1 + carried 1? In that case, the result is 11, which means that column's result is 1, and we carry 1 to the next column. Below is an example of adding two binary numbers that shows all…
