Program that defines template to find minimum value in an array

Posted By: Easy Tutor     Category: C++ Programming     Views: 24315

Write a program that finds minimum integer, smallest character and minimum decimal from an array using template class.

Code for Program that defines template to find minimum value in an array in C++ Programming

#include <iostream.h>
#include <conio.h>

template <class T>
T findMin(T arr[],int n)
{
    int i;
    T min;
    min=arr[0];
    for(i=0;i<n;i++)
    {
         if(min > arr[i])
        min=arr[i];
    }
    return(min);
}


void main()
{
    clrscr();
    int iarr[5];
    char carr[5];
    double darr[5];

    cout << "Integer Values \n";
    for(int i=0; i < 5; i++)
    {
        cout << "Enter integer value "  << i+1 << " : ";
        cin >> iarr[i];
    }

    cout << "Character values \n";
    for(int j=0; j < 5; j++)
    {
        cout << "Enter character value " << j+1 << " : ";
        cin >> carr[j];
    }


    cout << "Decimal values \n";
    for(int k=0; k < 5; k++)
    {
        cout << "Enter decimal value " << k+1 << " : ";
        cin >> darr[k];
    }
    //calling Generic function...to find minimum value.
    cout<<"Generic Function to find Minimum from Array\n\n";
    cout<<"Integer Minimum is : "<<findMin(iarr,5)<<"\n";
    cout<<"Character Minimum is : "<<findMin(carr,5)<<"\n";
    cout<<"Double Minimum is : "<<findMin(darr,5)<<"\n";

    getch();
}

here is a better way of doing this because your code would not compile


[
#include <iostream>
#include <array>
#include <string>
using namespace std;
template<typename T>
T maxValue(T list[],const int& size)
{
T currentMax = list[0];

for (int i = 0; i < size; i++)
{

if(currentMax < list[i])
{
currentMax = list[i];
}
}
return currentMax;
}

int main()
{
int intArray[] =
{
1, 2, 4, 2, 5, 3, 1
};
cout << "Max int value is " << maxValue(intArray, 7) << endl;

double doubleArray[] =
{
1.4, 2, 0.4, 2, 0.5, 3, 1
};
cout << "Max double is " << maxValue(doubleArray, 7) << endl;

string strings[] =
{
"abc", "cbs", "nbc"
};

cout << "Max string is " << maxValue(strings, 3) << endl;

return 0;
}
