Question

25. (15 pes) Write the C++ code for a function that receives three double numbers. The function should calculate the average of the three numbers and them returm the result. Name the function conm Name the fornal parameters aumi, nu compAverage function. In addition, write a statement that invokes the compAverage f assigns its arguments: 14.50, 18.72, and S3.1 function and its return value to a double variable named answer. Use the following mumbers as the 26, (5 pts) Write the C++ statement to assign the result variable below the squared value of S、Use the pow function to produce the result

Answer 1

#include<iostream>
#include<math.h>
using namespace std;
//25
double compAverage(double num1,double num2,double num3)
{
   //returning average
   return (num1+num2+num3)/3;
}
int main()
{
   double answer = compAverage(14.50,18.72,88.11);
  
   cout<<"Average of 14.50,18.72,88.11 :"<<answer<<endl;
   //26
   int result = pow(8,2);
  
   cout<<"square value of 8 :"<<result<<endl;
   return 0;
}

output:

Average of 14.50,18.72,88.11 :40.4433
square value of 8 :64
