First, we get the current working directory using the Getwd() function of the os package. Then, we get the absolute path of the current working directory using the Abs() function of the filepath package. We get the absolute path of the current working directory and add the name of the file to copy to the source variable. We get the absolute path of the current working directory and add the name of the destination file to the destination variable. We create the destination file using the Create() function of the os package. We copy the source file to destination using the CopyFile() function. This function opens the source file using the Open() function of the os package
