Question

I need help with the following assignment:

Write an application named DailyTemps that continuously prompts a user for a series of daily high temperatures until the user enters a sentinel value of 999. Valid temperatures range from -20 through 130 Fahrenheit. When the user enters a valid temperature, add it to a total; when the user enters an invalid temperature, display the error message:

Valid temperatures range from -20 to 130. Please reenter temperature.

Before the program ends, display the number of temperatures entered and the average temperature.

This is what I currently have:

using System;

class Program
{
static void Main(string[] args)
{
int number;
int sum=0;
  
Console.WriteLine("Please enter your series of high temperatures and enter 999 when you are done.");
do{
number = int.Parse(Console.ReadLine());
for(int i=1;i<-20 || i>130;i++)
{
Console.Write("Valid temperatures range from -20 to 130. Please reenter temperature.");
}
for(number!=999)
{
sum+=number;
}
else
break;
}
while( number= 999);

// Now sum has accumulated the sum of all numbers excluding 999
Console.WriteLine("The sum is {0}", sum);
}
}

C# Program:

using System;

class Program
{
static void Main(string[] args)
{
int number=0;
int sum=0;
int temp;
  
Console.WriteLine("Please enter your series of high temperatures and enter 999 when you are done.");
do{
temp = int.Parse(Console.ReadLine());
if(temp==999)
break;
if(temp<-20 || temp>130)
Console.WriteLine("Valid temperatures range from -20 to 130. Please reenter temperature.");
else{
sum+=temp;
number++;
}
}while(true);

// Now sum has accumulated the sum of all numbers excluding 999
Console.WriteLine("The sum is {0}", sum);
Console.WriteLine("Number of temperatures entered is {0}",number);
Console.WriteLine("Average temperature is {0}",(float)sum/number);
}
}

Output:
