Code:

#include<iostream.h>
#include<conio.h>

int arraymax(int arr[],int size)
{
 int max=0;
 for(int i=0;i<size;i++)
 {
  if(arr[i]>max)
  {
  max=arr[i];
  }
 }
return max;
}

void main()
{
clrscr();

int i,n, A[100];
cout<<"Enter the number of elements needed in the array[less than 100]: ";
cin>>n;

cout<<"\nEnter the elements: ";

for(i=0;i<n;i++)
cin<<a[i];

cout<<"\nLargest element in the array is: "<<arraymax(A,n);
getch();
}




Output:
Enter the number of elements needed in the array[less than 100]: <number less than 1000>

Enter the elements: <number 1>
<number 2>
<number 3>
<.>
<.>
<number n>

Largest element in the array is: <largest of those^ numbers>
