Write a C$++$ program that prompts the user to enter their name and location point $($x$,$ y$)$ on a map.The program will check whether the point is within the a random sized, map width of $20$ and height $20$ centered at $0,0$ ie a$(-10,-10),$b$(-10,10),$c$(10,10),$ d$(10,-10).$

$-$Use a function to check if the location is valid.

$-$Use a function to create the random sized map.

$-$Use if else.

$-$Use a global variable and$/$or logical operators
