CODE:

#include<iostream>
using namespace std;

int smaller(int &a,int &b){ //receiving inputs as refereces
   if(a>b) //checking for small amoung two numbers
       return b; //return the smaller number
   else
       return a;
}
int main(){
   int m,n,small;
   cout<<"Enter two numbers: ";
   cin>>m>>n; //input the two numbers
   small=smaller(m,n); //calling function with refernces.
   cout<<"Smaller number is: "<<small; //printing the smaller value.
   return 0;
