Write a complete C program consisting of the main function and a void function. The program uses the void function to display the following menu: 1. Square root of sum 2. Logarithm to base e of sum of squares Please enter your choice The program then prompts for and reads two values x and y each of type double. It then uses a switch statement to do the following, based on the selected choice: • Choice 1: The program displays the value of sqrt(x + y) if x + y is greater than or equal to zero; otherwise it displays an appropriate error message. • Choice 2: The program displays the value of log(x * x + y * y) if x2 + y2 is greater than zero; otherwise it displays an appropriate error message.
