Error Check for reading from text files

-----------------------------------

In the program I am making, the user inputs the filename of the text file that they would like to open. If this file does not exist, the program instantly crashes. Is it possible to make some sort of error check to see if the file exists or not before trying to open it? Thanks in advance.
