Write a C program that gets 4 integer values from the user, namely, x1, x2, y1, and y2, and then calculates and returns the distance according to the above formula. Use whatever format for entering your data you like. Your program should prompt the user for these values, accept input from the keyboard, and then print out the result. You will have to execute the program four times to cover the test cases below (feel free to use a loop if you want to work ahead). Include a screenshot (or four) that shows the results for the following values: 1) (2,3), (4,5) 2) (4,3), (-6,-5) 3) (-1,3), (4,-2) 4) (-9,-12), (-7, -8) Note that these inputs are (x, y) pairs. Input can be as listed above or simply numbers separated by spaces, e. g., 2 3 4 5. You should use the function double sqrt (double), found in , to calculate the square root. Print your answers out with two decimal places after the decimal point.
