Create the equivalent of a four-function calculator. The program should ask the user to enter a number, an operator, and another number. (Use floating point.) It should then carry out the specified arithmetical operation: adding, subtracting, multiplying, or dividing the two numbers. Use a switch statement to select the operation. Finally, display the result. When it finishes the calculation, the program should ask whether the user wants to do another calculation. The response can be ‘y’ or ‘n’. Some sample interaction with the program might look like this: Enter <first number> <operator> <second number>: 10 / 3 answer = 3.333333 Do another (y/n)? y Enter <first number> <operator> <second number>: 12 + 100 answer = 112 Do another (y/n)? n

- C-Program for blood pressure. The program (screenshot below) compares the systolic & diastolic measurements to output whether the blood is (low, ideal, pre-high, or high) The code I wrote is able to successfully determine the blood pressure type as long as it lies within the same range. However, if it goes outside that range it prints an error. FOR EXAMPLE**** PLEASE READ*** If the user inputs their systolic variable as 100 and their systolic as 90, it will print an error. If the systolic & diastolic measurements are vastly different the program prints an error, if you could help resolve this issue it would be greatly appreciated.arrow_forwardRewrite the following code segment using conditional operators (?/:)arrow_forward(a) Write two different techniques to declare and initialize a variable with an example.

- Which of the following statements about Python expressions is true (choose all that apply). a. In mathematical expressions, the operand can be a mathematical expression itself. b. The assignment operator (-) has higher precedence than subtraction (-). c. To negate a value of a variable you use the (--) operator. d. In Python operators such (--) and (-) allow you to compare between values of different variables. Assuming that data is a correctly created list, then the fact that lists are mutable means that the following statement: data[9] max (data) / data[-3] %3D O a. Is illegal. O b. Maybe illegal if the list contains floats. Oc is fully correct. O d. Can be executed if and only if the list contains at least nine elements. O e.
