Task $2-$ Rectangular to Polar Coordinates

Write a program that converts rectangular to polar coordinates. Your program should have three user defined functions;

getrec$()-$ this function obtains the rectangular coordinates and accepts the argument by reference.

polar$()-$ this function calculates the polar coordinates and accepts the arguments by reference and value. First two arguments by value and the other two by reference.

showit$()-$ this function displays the polar coordinates and accepts the argument by value.
