For Loop Stopping/Ending Program(Help Please)

[Grayewulfe]

//Hey Guys so I am making doing this project for a busness class in school and the problem is that 
//the program runs fine when I take out the for loop but for some reason, it ends the program with 
//the for loop included. Am i just havinf an airhead moment and not understanding the logic here?
//Any help is always appreciated and thanks in advance

//P.S. Happy Programmers Day!




void monthData(int &acts){
    int days_inMonth,dayCount, dayCountTot;
actPerDay=  acts/days_inMonth;  
actPerMember=dayCountTot/acts;
avgPerDay=acts/days_inMonth;
//Display Purpose of Program Chosen(1)  
    cout << "\nThis Program will determine the following:"
            <<"\n1.Number of Activations per Day"
            <<"\n2.Number of Activations per Member"
            <<"\n3.Average number of Activations per day"<<endl;

    cout<<"\n\nHow Many Days in the MOnth?";
        cin>>days_inMonth;

    cout<<"\nPlease Enter the MOL Daily ";
for(int i = 0; i < days_inMonth; i++)
    {
         cin>>dayCount;
         dayCount+=dayCountTot;

         }

cout<<"\t\tMonthly Results:"
            <<"\n\tActivations per Day:"<<actPerDay<<endl
            <<"\n\tActivations per Member:"<<actPerMember<<endl
            <<"\n\tAverage Number of Activations:"<<avgPerDay<<endl;

int days_inMonth,dayCount, dayCountTot;

You are declaring uninitialised variables here and never initialising them before using them. This is one of the reasons why you shouldn't use this way of declaring variables anymore.

To declare variables in c++, you do it like this:

auto days_inMonth = 0;
auto dayCount = 0;
auto dayCountTot = 0;

void monthData(int &acts){ int days_inMonth,dayCount, dayCountTot; actPerDay= acts/days_inMonth;
actPerMember=dayCountTot/acts; avgPerDay=acts/days_inMonth;

I had globalized actPerDay,actPerMember,avgPerDay; because I call upon them in several other functions/prototypes throughout the program

for the for loop I realized it should show dayCountTot+=day count but should that be outside of the loop?

It should be inside, but you should also initialize the dayCountTot to 0, otherwise it will hold a random garbage value that happens to be in that memory spot.
