Question

Given an array temps of doubles, containing temperature data, compute the average temperature. Store the average in a variable called avgTemp, which has already been declared. Besides temps and avgTemp, you may use only two other variables -- an int variable k and a double variable named total, which have been declared .

Answer 1

Answer:

#include <iostream>

using namespace std;

int main() {

   double temps[10]={32.2,30.1,33.5,32.8,35.0,36.7,36.8,35.6,34.9,36.9};//initialized 10 temps values.

   double avgTemp,total=0;//two varaibles declared.

   for(int k=0;k<10;k++)//for loop to calculate the average..

   {

       total+=temps[k];//adding temperature values to the total..

   }

   avgTemp=total/10;//calcualting the average..

   cout<<"The average temperature is "<<avgTemp<<endl;//printing the average temperature.

return 0;

}

Output:-

The average temperature is 34.45.

Explanation:

The above written code is in C++. An array of double temps is initialized with arbitrary 10 values.Then the average is calculated using the integer k and the average is stored in the variable avgTemp. Then it is printed on the screen.
