// Variables

int firtstNumber = 0;

char chFirstNumber[10];

int secondNumber = 0;

int countIntDivSecondNumber = 0;

// Input data

while (firtstNumber < 100 || secondNumber < 100) {

 cout << "Firtst Number = ";

 cin >> firtstNumber;

}

// Convert int to char (save to chFirstNumber)

_itoa_s(firtstNumber, chFirstNumber, 10);

// arithmetic average of the integer divisors

for (int i = 1; i < secondNumber; i++) {

// Output solution
