    Newbie Question on a Loop/If-Else thing

    Here is some code that is probably all f'd up:

    int main()
    {
    int year;
    char ans;
    ans = y;
    while(ans==y)
    {
    cout<<"What Year?";
    cin>>year;
    cout<<endl<<year<<endl;
    date(year);
    cout<<"Would you like another date? (y/n)";
    cin>>ans;
    }
    cout<<"Thank you"<<endl;
    return 0;
    }

    It keeps telling me " y undeclared first use the function, i have tried a million variation, i dont know what the deal is. Here is the same code in If-Else format, i think.

    int main()
    {
    int year;
    bool ans;
    cout<<"Would you like to enter a date?(y/n):";
    cin>>ans;
    if(ans==y)
    {
    cout<<"Enter the year(for example, 1999):";
    cin>>year;
    cout<<endl<<year<<endl;
    date(year);
    cout<<"Would you like to enter another date?(y/n):";
    cin>>ans;
    }
    else
    {
    cout<<"Thank you"<<endl;
    }
    return 0;
    }

    Any help would be great. Oh yeah the if then has the same y is undeclared thing.

    try this

    int main()
    {
    int year;
    char ans;
    ans = y;
    while(ans==y)

    with this code you have created an endless loop. ans will always equal y in this case. By the way, your syntax should be:

    ans = 'y';
    if(ans=='y')

    you need to get the input from the user first and then do the while loop to check and see if it is y.

    Thanks, i figured it out, well, you figured it out anyways. I switched back to while and put the ' ' around y it it works fine now.
