Question

Write a C++ program that takes in a set of daily average temperatures (up to a maximum of 30):
1.Ask the user for a temperature
2.If the user enters a -1 then stop asking for temperatures.
3. After the user is done entering temperatures:
a. Print out the temperatures entered.
b. print out the average, high and low temperatures.
To get average, use:
average = (sum of temps) divided by (count of temps)
to get max or min, either keep track of the max or min
as the user enters a number or you can do this later when
printing the temperatures. Do this by comparing the current max
value to the number and replacing it if it is bigger (smaller for min).
for example:
if(array[i] > max)
max = array[i];
you can initialize max to 0 and min to some large number (1000) for
this exercise but in the future (during exams) you should set it to the
first element in the list.
NOTE: Use floating point type for all numbers to prevent truncating the decimal part of the average.
Requirements:
You must enter temperatures into an array and use this array for calculating the average and print out the temperatures.
Use two loops, one for entering numbers and one for printing the temperatures.

Code:

#include <iostream>
using namespace std;
int main() {
// array named temp to store entered temperature values
int temp[30];
int i,temperature;
i=0;
// given that we can read temperature upto maximum of 30
// so we have to iterate loop through 30 times
while(i<=30){
// taking temperature form the user
cout << "Enter temperature (enter -1 to quit):" <<endl;
cin >> temperature;
// if the temperature value is -1
// we have to quit so we breaking the loop
if (temperature == -1){
break;
}
// if not -1 then add that temperature to the array by incrementing the array index
else{
temp[i++]=temperature;
}
// here i becomes the number if number of temperatures
}
// after reading values
// intialise the values of min to some maximum value amd max to some minimum value
int max = -100,min = 1000,sum=0;
// loop for printing the temperatures and finding maximum and minimum temperatures
cout << "The temperatures are: ";
for (int j=0;j<i;j++){
// printing temperature
cout << temp[j] << " ";
// finding the sum of all temperatures
sum = sum+temp[j];
// checking current value of the array is greater than the previous max
if(temp[j]>max){
// if greater then update the max value
max = temp[j];
}
// checking current value of the array is less than the previous min
if(temp[j]<min){
// update the min value
min = temp[j];
}
}
// after the end of the loop the values of the max and min are the
// maximum and minimum temperatures in the given set of temperatures
cout <<endl;
// finding avg of the temperatures using the sum computed in the loop
double avg = (double)sum/i;
// printing the values
cout << "The average temperature is: " << avg << endl ;
cout << "The maximum temperature is: " << max << endl ;
cout << "The minimum temperature is: " << min << endl ;
