Write a C program to calculate the distance, midpoint and slope between two endpoints. Your

program should satisfy the following requirements

a$.$ Provide the user with a menu that offers the following options; calculate distance, calculate

midpoint and calculate slope.

b$.$ Prompt the user to enter two endpoints. Each point is defined by x$-$ and y$-$coordinates. For

example point A $($x$1,$ y$1)$ and point B$($x$2,$ y$2)$

c$.$ Beside function main$(),$ the program needs to define three $(3)$ user$-$defined functions as

described in Table $6.$ The sample output of this program is shown in Figure $5.$
