File Existance
If I run the above line of code and test.txt does not exists, is there some sort of return code that I can check to verify that it does not exist?Code:ofstream a_file("test.txt", ios::nocreate);
Ex.Code:ofstream a_file("test.txt", ios::nocreate); if (SOME_CONDITION) { //file does not exist, do something } //file does exist, do something else
If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein

Thanks
