How to Get Largest and Smallest Number in an Array in C++

Program 1

// find largets element from array
#include<iostream>
#define clrscr() system("cls")
using namespace std;

int main()
{
      int ar[100],i,n,max,p;
      clrscr();
      xyz:cout<<"Enter the limit\n";
      cin>>n;
      if(n>100)
      {
        cout<<"\nInvalid limit pls enter 0 to 100";
        goto xyz;
      }
      else
      {
          cout<<"\nEnter elements in array\n";
          for(i=0;i<n;i++)
          cin>>ar[i];
          max=ar[0];
          p=0;
          for(i=1;i<n;i++)
          {
              if(ar[i]>max)
              {
                max=ar[i];
                p=i;
              }
          }
          cout<<"\n\n***Largets element is*** : "<<max;
          cout<<"\n\n***Position is *** : "<<++p;

      }


}

Program 2

// find smallest element from array
#include<iostream>
#define clrscr() system("cls")
using namespace std;

int main()
{
      int ar[100],i,n,min,p;
      clrscr();
      xyz:cout<<"Enter the limit\n";
      cin>>n;
      if(n>100)
      {
        cout<<"\nInvalid limit pls enter 0 to 100";
        goto xyz;
      }
      else
      {
          cout<<"\nEnter elements in array\n";
          for(i=0;i<n;i++)
          cin>>ar[i];
          min=ar[0];
          p=0;
          for(i=1;i<n;i++)
          {
              if(ar[i]<min)
              {
                min=ar[i];
                p=i;
              }
          }
          cout<<"\n\n***Smallest element is*** : "<<min;
          cout<<"\n\n***Position is *** : "<<++p;

      }
