Program in C and C++ to find the second largest element in an array of n elements

CPP

#include<stdio.h>
#define size 25
 int Second_Max(int a[],int *n)
   {
      int l,sl,i;
   for(l=a[0],i=0;i<*n;i++)
    {
     if(a[i]>l)
       l=a[i];
  } 
   for(sl=0,i=0;i<*n;i++)
    {
     if(a[i]>sl&&a[i]!=l)
       sl=a[i];
  } 
 return sl;
   }
   int main(void)
    {
     int a[size],i,n;
     printf("Enter the size of array:-");
     scanf("%d",&n);
     if(n>size)
      {
       printf("Invalid array size.");
       return 0;
   }
  printf("Enter %d numbers:-",n);
  for(i=0;i<n;i++)
    scanf("%d",&a[i]);
  int sl=Second_Max(a,&n);
  printf("Second largest element = %d",sl);
  return 0;
 }

#include<iostream>
 using namespace std;
 int Second_Max(int a[],int &n)
   {
      int l,sl,i;
   for(l=a[0],i=0;i<n;i++)
    {
     if(a[i]>l)
       l=a[i];
  } 
   for(sl=a[0],i=0;i<n;i++)
    {
     if(a[i]>sl&&a[i]!=l)
       sl=a[i];
  } 
 return sl;
   }
   
   int main(void)
    {
     const int size=25;
     int a[size],i,n;
     cout<<"Enter the size of array:-";
     cin>>n;
     if(n>size)
      {
       cout<<"Invalid array size.";
       return 0;
   }
  cout<<"Enter "<<n<<" numbers:-";
  for(i=0;i<n;i++)
    cin>>a[i];
  int sl=Second_Max(a,n);
  cout<<"Second largest element = "<<sl;
  return 0;
 }

Output:-

Second method
