Question

Write a program that calculates the average rainfall for three months. The program should ask the user to enter the name of each month, such as June or July, and the amount of rain (in inches) that fell each month. The program should display a message similar to the following:
The average rainfall for June, July< And August is 6.72 inches.

Answer 1

#include <conio.h>
#include <iomanip>
#include <iostream>

using namespace std;

const string MONTH_NUMBERS[3] = { "1st", "2nd", "3rd" };

int main()
{
string monthes[3];
double rain[3];
double average = 0;

for (char n = 0; n < 3; n++)
{
cout << "Enter the name of the " << MONTH_NUMBERS[n] << " month: ";
cin >> monthes[n];

cout << "Enter the amount of rain fell during this month (in inches): ";
cin >> rain[n];

average += rain[n];
cout << endl;
}

average /= 3;
cout << "The average rainfall for " << monthes[0] << ", "
<< monthes[1] << " and "
<< monthes[2] << " is "
<< setprecision(2) << average << " inches." << endl;

_getch();
return 0;
}
