Answer 1

Functions that have one or more generic type parameters are referred to as generic functions.

How to write a generic function finds largest among the three values ?

Functions that have one or more generic type parameters are referred to as generic functions. They could be standalone functions or methods in a class or struct. A single generic declaration essentially declares a family of functions, with the sole difference being the actual type parameter's substitution with a different one.

#include <iostream>

using namespace std;

int main() {

      double n1, n2, n3;

cout << "Enter three numbers: ";

   cin >> n1 >> n2 >> n3;

    check if n1 is the largest number

   if(n1 >= n2 && n1 >= n3)

       cout << "Largest number: " << n1;

   check if n2 is the largest number

   else if(n2 >= n1 && n2 >= n3)

       cout << "Largest number: " << n2;

   

    if neither n1 nor n2 are the largest, n3 is the largest

   else

       cout << "Largest number: " << n3;

   return 0;

}

Output

Enter three numbers: 2.3 ,8.3 ,-4.2

Largest number: 8.3
