(Function Template Overloading) Overload function template printArray of Fig. 14.1 with a nontemplate version that prints an array of character strings in neat, tabular, column format.

Question

What will be an ideal response?

Answer 1

```
// Using template functions
#include
#include
#include
using namespace std;

// function template printArray
template< typename T >
void printArray( T const * array, int size )
{
// display elements of array
for ( int i = 0; i < size; i++ )
cout << array[ i ] << ' ';

cout << endl;
} // end function printArray

// function that prints array of strings in tabular format
void printArray( const string stringArray[], int size )
{
// display elements of array
for ( int i = 0; i < size; i++ )
{
cout << setw( 10 ) << stringArray[ i ];

if ( ( i + 1 ) % 4 == 0 ) // create rows
cout << '\n';
} // end for

cout << endl;
} // end function printArray

int main()
{
const int ACOUNT = 5; // size of array a
const int BCOUNT = 7; // size of array b
const int CCOUNT = 6; // size of array c
const int SCOUNT = 8; // size of array strings

// initialize arrays
int a[ ACOUNT ] = { 1, 2, 3, 4, 5 };
double b[ BCOUNT ] = { 1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7 };
char c[ CCOUNT ] = "HELLO"; // 6th position for null
string strings[ SCOUNT ] =
{ "one", "two", "three", "four", "five", "six", "seven", "eight" };

cout << "Array a contains:\n";
printArray( a, ACOUNT ); // integer template function

cout << "\nArray b contains:\n";
printArray( b, BCOUNT ); // float template function

cout << "\nArray c contains:\n";
printArray( c, CCOUNT ); // character template function

cout << "\nArray strings contains:\n";
printArray( strings, SCOUNT ); // function specific to string arrays
} // end main
```
Array a contains:
1 2 3 4 5
Array b contains:
1.1 2.2 3.3 4.4 5.5 6.6 7.7
Array c contains:
H E L L O
Array strings contains:
one two three four
five six seven eight
