C++ program to find max and min in the array using function

#include<iostream>
using namespace std;
int arr_max_min(int arr[],int num);
int main()
{
int  num,i,arr[100],result;
cout<<"Enter the size of the array\n";
cin>>num;
cout<<"Enter numbers in the array one by one \n";
for(i=0;i<num;i++)
{

cin>>arr[i];
}
result=arr_max_min(arr,num);
}
int arr_max_min(int arr[],int num)
//displaying output in the function declartion part
{
int max,min,i;
max=arr[0];
for(i=0;i<num;i++)
{
if(arr[i]>max)
max=arr[i];
}
//return max; as we are already printing the output so function can not return anything
cout<<"The maximuum in the array is \t"<<max;
for(i=0;i<num;i++)
{
min=arr[0];
if(arr[i]<min)
min=arr[i];
//return min;

}
cout<<"\nThe minimum in the array is\t"<<min;
}

OUTPUT:

Enter the size of the array

3

Enter numbers in the array one by one 

9 

6

3

The maximuum in the array is 9

The minimum in the array is 3
