For this assignment, write a C$++$ program to calculate and display the gravitational force between twoobjects.Basic Program LogicThe first thing to do in the program is to create any variables that are needed to hold$/$save informationfor the program. To determine how many variables are needed, think about the information that will beentered by someone using the program and whether it is important for that information to be saved.Think about any calculations that will be performed by the program and whether the results of thecalculations need to be saved. To determine the data type for the variables, think about what valuessomeone using the program will be entering or what kind of results will be produced by anycalculations. $($Note: to ease into writing this first program, the data type for the variables has beenspecified below.$)$
