Thread: Help on array comparison

Ok.. trust me, this is the final question from me..

Write a function template called printArray that takes an arbitrary array type and and two additional integer arguments, lowSubscript, highSubscript. A call to this function will print only the designated portion of the array. Validate lowSubscript and highSubcript if either is out of range or if highSubscript is less than or equal to lowSubscript, printArray should return 0; otherwise printArray should return the number of elements printed

really confused with this... any guidance on this?? pls

the template..

i did normal main program by doing a function and initialized two arrays.. but only later realized we need to use the template for it..

oh..

thanks sir.. will try to work on this template (pardon the pun)

Code:

#include<iostream>
using namespace std;

template < class T >
T printArray(const T *array, const int count,int lowsub,int highsub)
{
	if(highsub>count || highsub<=lowsub)
		return 0;
	else
	{
		for (int i=lowsub; i<=highsub; i++)
			cout<<array[i]<<" ";
		cout<<endl;
		return array[i];
	}
	
}

template < class T >
void printArray(const T *array, const int count)
{
	for (int i=0; i<count; i++)
		cout<<array[i]<<" ";
	cout<<endl;
}

void main()
{
	const int icount = 5,dcount = 6,ccount = 4; 
	int i[icount] = {2,5,3,7,4};
	double d[dcount] = {2.4,3.7,1.5,6.5,8.2,4.3};
	char c[ccount] = "RAY";

	cout<<"Array i contains : \n";
	printArray(i,icount);
	printArray(i,icount,2,4);
	cout<<"Array d contains : \n";
 	printArray(d,dcount);
	printArray(d,dcount,2,5);
	cout<<"Array c contains : \n";
	printArray(c,ccount);
	printArray(c,ccount,0,1);
}

my effort...

is this right?
