Hi all, Hopefully someone can help me out. I'm new to programming, and for class, we have to make a program that determines the day of the week of a specific date that the user enters. I keep getting an error "expression result unused" and I can't figure out why. Here's part of my source code: Code: int month, day, years, LTYear, total, Gtotal; cout<<"Input date in M/DD/YYYY format. (ex. 2/07/1990 or 10/13/2010)"<<endl; cin>>month; day; years; if (month==2 && years%4==0 && years%100!=0 && day>=30) cout<<"Invalid day.\n"; else if (month==2 && day>=29) cout<<"Invalid day.\n"; if (day<=1||day>31) cout<<"Invalid day.\n"; if (years<1900 || years>2099) cout<<"Invalid year.\n"; I get the issue when I try to get the cin for day and year. Any advice? Thanks in advance!
