I am getting these errors:

For displayList, line 8 says there are two parameters, but line 21 passes none.

When posting error messages, include the part of the error message that indicates the line number. Copy and paste the errors. It should have taken you directly to line 21 and 23. I am not sure where the third error is.

here is the whole error message:
1>d:\chargevalidation\chargevalidation\chargev.cpp(25): error C2660: 'displayList' : function does not take 0 arguments
1>d:\chargevalidation\chargevalidation\chargev.cpp(27): error C2660: 'displaySortlist' : function does not take 0 arguments
1>d:\chargevalidation\chargevalidation\chargev.cpp(28): error C2660: 'searchFile' : function does not take 0 arguments

each of your functions need parameters for each time you call them, such as displaylist(25, 2) your prototypes and your functions say they need 2 parameters each. but when you call them in main, it doesn't work because it's looking for those. the error message "function does not take 0 arguments" means that you tried to use 0 parameters, but it doesn't take 0, they take 2. So if you give your functions the proper arguments it should work
