What is an object? Inobject-oriented programming (OOP), objects are the things you think about first in designing a program and they are also the units of code that are eventually derived from the process. In between, each object is made into a genericclassof object, and even more generic...
How does debugging work in a Programming Language? Debugging is an invaluable tool for finding errors in programs prior to running them in real-world scenarios, including those which cannot possibly be recreated due to laboratory restrictions or testing environments. By running programs through debugger...
An enum is a user-defined type consisting of a set of named constants called enumerators. The colors of the rainbow would be mapped like this.: Now internally, the compiler will use an int to hold these and if no values are supplied, red will be 0, orange is 1 etc. What Is the Be...
