An **array** stores data. The data can be of any type, and each element represents a specific piece of information. 

# Algorithm 

Suppose there is a team of five players, ​and the oldest player is going to become the captain.

1. The array that stores the age of all the players will be traversed to find the maximum age. 

2. A variable named (`max`) that stores the maximum element found so far will be initialized. 
3. Initially, the first element will be set as the `max` and then the array will be traversed.
4. Each element will be compared with the `max`, and if the current element is greater than the `max`, the `max` will be set to the current element. 
5. Finally, the `max` is returned.

The following slides better explain this problem:

# Code 

The following codes find the outputs and maximum element in the array:

#include <iostream> 
using namespace std; 
  
int largest(int arr[], int n) 
{ 
    int i; 
      
    // Initialize maximum element 
    int max = arr[0]; 
  
    // Traverse array elements  
    // and compare every element with current max  
    for (i = 1; i < n; i++) 
        if (arr[i] > max) 
        {   
            max = arr[i]; 
        }
    return max; 
} 
  
// Driver Code 
int main() 
{ 
    int arr[] = {18, 24, 21, 27, 19};// ages of players
    int n = sizeof(arr) / sizeof(arr[0]); 
    cout << "Maximum element is " 
         << largest(arr, n); 
    return 0; 
} 

class Test 
{ 
     static int arr[] = {18, 24, 21, 27, 19}; 
       
     // Method to find maximum in arr[] 
     static int largest() 
     { 
         int i; 
           
         // Initialize maximum element 
         int max = arr[0]; 
        
         // Traverse array elements from second and 
         // compare every element with current max   
         for (i = 1; i < arr.length; i++) 
             if (arr[i] > max) 
                 max = arr[i]; 
        
         return max; 
     } 
       
     // Driver method 
     public static void main(String[] args)  
     { 
         System.out.println("Maximum element is  " + largest()); 
        } 
 } 

Java

def largest(arr, n): 
  
    return max(arr) 
  
# driver code 
arr = [18, 24, 21, 27, 19] 
n = len(arr) 
  
print("Maximum element is ", largest(arr, n))

How to find the maximum element in an array

Initialize a max variable, traverse the array comparing elements, update max if necessary, and return max.
