Help with variables losing its stacks, and calculation with arrays

Terje Gundersen (35)
Hi, this is the program i am making. I'm not a student of c++ i received this
task from a friend who is. I'm doing this for fun, just to clarify that. However, with this program, i have errors that i have no idead why are there.
1. While running this program, sometimes the stack around variable nrofdays, mintemp and maxtemp are corrupted, or lost. That is beyond me.
2. I'd also like some advice as to how the calculation at the end is'nt working. This is obviously a beginner problem, that has to do with understanding arrays.

// Program shall prompt the user how many days it is in the month the user is stat tracking. ( has to be 28-31)
// mintemp has to be between -70 and 70, while maxtemp has to be between mintemp and 70. Downpour has to be from 0 to 200.
// Then, the program will state the average minimal temperature, average maximal temperature, and average downpour.

	 cin >> nrofdays;
	 if (nrofdays > 31)
		 nrofdays = 0;
 }
	 while ( nrofdays < 28);

for (int i = 0; i < nrofdays; i++) { // This is a for loop with 3 do-while loops in it to ensure error free inputs

	do {
	cout << "Enter minimum temperature for day " << i + 1 << ". (-70 - 70)" << endl;
	cin >> mintemp[i];
	if (mintemp[i] > 70)

		maxtemp[i] = 0;
	else if (maxtemp[i] > 70)
		maxtemp[i] = 0;
}
