Simple Function Template Program Example Get Maximum Number


Generic Programming

Templates are a feature of the C++ programming language that allows functions and classes to operate with generic types

Function Template Definition

A function template behaves same as normal function except that the template works with different data types.

Function Template Syntax

template <class identifier> function_declaration;
template <typename identifier> function_declaration;

templete_identifier fn_name(templete_identifier .. args) {
 return ...
}

Example Program

// Header Files
#include<iostream>
#include<stdio.h>
#include<conio.h>

using namespace std;

// Template Declaration

template<class T>

// Template Function
T getMaximun(T x, T y) {
    if (x > y)
        return x;
    else
        return y;
}

int main() {
    int a, b, i;
    float c, d, j;

    cout << "Function Template Programs : Get Maximum Number \n";
    cout << "Enter A,B values(integer):";
    cin >> a>>b;
    i = getMaximun<int>(a, b);
    cout << "Result Max Int : " << i;

    cout << "\n\nEnter C,D values(float):";
    cin >> c>>d;
    j = getMaximun<float>(c, d);
    cout << "Result Max Float : " << j;

    getch();
    return 0;
}

Sample Output

Function Template Programs : Get Maximum Number
Enter A,B values(integer):56
89
Result Max Int : 89

Enter C,D values(float):17.99
9.01
Result Max Float : 17.99
