Write the code and trace for the following:

1. Design an algorithm that will receive input of two integers and display to the screen their sum, difference, product, and quotient. Do not allow division by zero to occur.

2. Design an algorithm that will read two numbers and an integer code from the screen (print a menu of the choices first). If the code is 1, compute the sum of the two numbers. If the code is 2, compute the difference of the first number minus the second. If the code is 3, compute the product. If the code is 4 and the second number is not 0, compute the quotient (divide the first number by the second). If the code is not 1,2,3, or 4, display an error message. Finally, display the two numbers, the code, and the result (echo the input).
