""" MENU::::::: This is the second version of my previous work done on the "image info generator" please check my PREVIOUS VERSION too!! WANT TO KNOW THE : THEN ENTER this input in the following order:: 1# type of lens* nature of the image(virtual or real),,object distance,,image distance 2# focal length* type of the lens,,object distance ,, image distance,,type of the image 3# object distance * location of the image(behind or after the lens),,focal length,,image distance,,type of the lens 4# image distance from the lens** focal length,,object distance,,type of lens(concave/convex)**0 5# object height** magnification,,nature of the image(virtual or real),,image height 6# image height** magnification,,object height,,nature of the image(virtual or real) 7# power of the lens* focal length,,type of the lens 8# mangnification* object distance,,image distance,,nature of the image(virtual/real) 9# locaton of the image* type of the lens,,focal length,,object distance 10# nature of the image* location of the image 11# if you want to know to know all the properties******** type of the lens,,focal length,,objet distance,,object height please enter what you want to know then enter the requirred input as stated sideways happy you!!!!!!!!!!! happy coding!!!!!! *****please follow the ORDER OF GIVING THE INPUTS as stated above for no errors**** enter the inputs in CMS but dont write the units IF YOU FIND SOME ERROR PLEASE HELP ME KNOW!!!!!!!!!!!
