Largest Number c programming language

For Example:
Given Array: 1 8 3 9 4
Output: 9

// Write a c program to the find the largest number in an array.
    #include <stdio.h>
    
    int main()
    {
        int n;
        printf("Enter the size of array : ");
        scanf("%d", &n);
        
        int arr[n];
        
        printf("Enter the element : ");
        for(int i=0; i<n; i++){
            scanf("%d", &arr[i]);
        }
        
        int max = arr[0];

            if(arr[i]>max){
                max = arr[i];
            }

        return 0;
    }
