Create an Array Summing Function Template in CPP

//A program to define a function template

//for summing an array of integers and an

//array of floating point numbers//

#include <iostream.h>

#include<conio.h>

template<class T> T sum (T *array, int n)

{

   T temp = 0;

   for(int i=0; i<=n-1; i++)

   temp = temp+array[i];

   return(temp);

}

int sum (int *a, int n);

float sum(float *b,int n);

void main()

{

   clrscr();

   int n = 3,sum1;

   float sum2;

   static int a[3] = {1,2,3};

   static float b[3] = {1.1,2.2,3.3};

   sum1 = sum(a,n);

   cout << " sum of the integers = " << sum1 << endl;

   sum2 =sum(b,n);

   cout << " sum of the  floating point numbers = " << sum2;

   cout<< endl;

   getch();
