In the cardSearch function, do you mean to read the files as input, ifstream instead of ofstream?
gunnerfunner (2127)
monstercardFile is an ofstream object and so you need to use the insertion operator << and not the extraction operator >> (as a rule of thumb the arrows indicate whether the data is going to the stream or coming from the stream). So check throughout your program that the operators and corresponding fstream objects match.

You seem to have chucked in bunches of cin ignore, clear, get at various points in your code. Do make sure you fully understand what each of these methods do.

Return 0 will end the entire program but if you wish to (a) give the user the option to go back to the start menu and choose from New Cards, Search Cards or Exit Program again or (b) move on to some other procedures before quitiing main() then a bool variable to quit the switch-case statements is more efficient. Here's something I posted recently on this: http://www.cplusplus.com/forum/beginner/201427/

Finally, please use code-tags for posting code

Thank you for the help gunnerfunner. I have tried the code tags but couldn't figure out how to use them it never turned out right.

How might I create an edit function to edit the data of a specified card?

Thank you for the help gunnerfunner. I have tried the code tags but couldn't figure out how to use them it never turned out right.

Edit your topic and wrap your code in [code] (Your code) [/code] tags.
gunnerfunner (2127)
You can't edit the data of a specified card under your current program as it doesn't capture the card object. To do that you first have to set up a Card class with data-members such as suit and face and then instantiate objects of this class inside your program. Then if your Card class has appropriate setter methods you can change the attributes of the specified card through these methods.
A recent example of the Card class on this forum that I'd contributed to: http://www.cplusplus.com/forum/beginner/201221/

Alrighty thank you for all your assistance.
