visual studio cannot start debugging because the debug target is missing

Question

Every time i run this and try to debug i get this message: visual studio cannot start debugging because the debug target is missing. I need to debug it first before i can turn it in as my teacher says it has syntax errors. Can anyone tell me what is debugging and syntax errors

Description: This program accepts as input the radius and height of a cylinder and computes the volume.
