Temp conversions

Hi Guys

Im trying to wirte a program that reads in 10 tempruratures then sends them
to a function which converts them to farhenheit. It compiles ok but its only converting and returning the first value as the output.

I guess I am making a very obvious mistake but cannot see where.

here is my code I appreciate any help on this:

Code:

#include <iostream>
#include <iomanip>

// function prototype
double celsius ( double[], const int );

// main function - begins program execution ////////////////////////////////////
//
int main ( void )
{
   const int ARRAY_SIZE = 10;
   
   double cel[ ARRAY_SIZE ] = { 0 };
   
   std::cout << "Enter 10 temp in celsius: ";
   
   for ( int i = 0; i < ARRAY_SIZE; i++ )
   {
      std::cin >> cel[ i ];
   }
   
   std::cout << "\nCELSIUS" << std::setw( 17 ) << "FARHENHEIT\n\n";
   
   for ( int i = 0; i < ARRAY_SIZE; i++ )
   {
      std::cout << cel[ i ] <<std::setw( 17 ) 
                << celsius ( cel, ARRAY_SIZE ) << std::endl;
   }
   
   std::cin.get(); // freeze console output window
   std::cin.ignore();
   
   return 0; // return value from int main
}

double celsius ( double x[], const int size )
{
   double farhenheit;
   
   for ( int k = 0; k < size; k++ )
   {
      // calculate conversion from celsius
      // to farhenheit
      int factor = 212 - 32;
   
      // convert celsius to farhenheit
      farhenheit = factor * x[ k ] / 100 + 32;
   }
   
   return farhenheit;
}

The obvious problem is that celsius() operates on an array to return a single value. It probably should operate on a single value to convert it. In such a case you can then loop over the array and use celsius() on each element.

Which is also the only way your formatting could possibly work.

Cheers guys
