Write a template function that returns the largest value and
Solution
#include<iostream>
 #include<vector>
//change Type to type of vector you want , if you want float type just change int to float
 #define Type int
 using namespace std;
template<typename type>
 void largeAndSmall(std::vector<type> &a,type &tmin, type &tmax)
 {
    tmax = a[0] , tmin = a[0];
    for ( int i = 0 ; i < a.size() ; i++ )
    {
        if( a[i] < tmin )
            tmin = a[i] ;
        if( a[i] > tmax )
            tmax = a[i] ;
    }
 }
int main()
 {
    std::vector <Type> int_arr;
   int_arr.push_back(3);
    int_arr.push_back(0);
    int_arr.push_back(9);
    int_arr.push_back(-8);
    int_arr.push_back(-1);
   cout<<\"Elements of vector are: \";
    for ( int i = 0 ; i < int_arr.size() ; i++ )
    {
        cout<<int_arr[i]<<\"\\t\";
    }
    cout<<endl;
    //print largest and smallest element in a vector
    Type max,min;
    largeAndSmall(int_arr,min,max);
    cout<<\"Max = \"<<max<<\"\\t\"<<\"Min = \"<<min<<endl;
 }
