Write a program in C to get the largest element of an array using the function

#include <stdio.h>
int main() 
{
	int i, n;
	float arr[100];
	printf("Enter the size : ");
	scanf("%d", &n);
	
	for (i = 0; i < n; ++i) 
	{
		printf("Enter number-%d: ", i+1);
		scanf("%f", &arr[i]);
	}
	for (i = 1; i < n; ++i) 
	{
		if (arr[0] < arr[i])
			arr[0] = arr[i];
	}
	
	printf("Largest element = %.2f", arr[0]);
	return 0;
}
