If statement inside loop not reading total right cout displaying wrong - c++

Question

Hello all I want to do is for last cout statement display whatever apartment has the highest rent and the apartment name. Right now it displays the total rent of all complexes enter and whatever the last complex name entered. I am stuck on this and could really use some help on this. I am new to c++ so please talk to me in layman terms it is hard for me to understand somethings.

totalAllRent = totalAllRent + rent;
if (totalAllRent > highestRentTotal)
{
highNameComplex = nameComplex;
highestRentTotal = totalAllRent;
}
averageRent = totalAllRent / numComplex;
}

outputFile.close(); //close the file

cout << "Complex Monthly rent Collected per Complex " << endl;
while (inputFile >> nameComplex)

for (int i = 0; i < numMonths; i++)
{
inputFile >> rent;
cout << nameComplex << " " << rent << endl;
if (rent == 0)
cout << "Warning one of the complexes submitted zero rent for one of the months " << endl;
}
}
cout << "Total rent collected for the company = " << totalAllRent << endl;
cout << " Average Monthly rent collected for the company = " << averageRent << endl;
cout << highNameComplex << "collect the most rent = " << highestRentTotal << endl;

Well...if it's me, I'll design the program as follows:
1. Define a vector<vector<double>> vvRents for storing the rents of all apartments by month.
2. Each element in vvRents stores the rents of all months of each apartment.
3. Once all data is collected, calculate summed rents of the year by apartment, and store the total rents in a new vector vTotalRents.
4. Use a max_element algorithm to pick the most expensive apartment.
You must include <vector> to use vector class, and include <algorithm> to use max_element.
