how to find max value of number in C code example

Example 1: find maximum number in array

#include <stdio.h>
int main() {
    int i, n;
    float arr[100];
    printf("Enter the number of elements (1 to 100): ");
    scanf("%d", &n);

    for (i = 0; i < n; ++i) {
        printf("Enter number%d: ", i + 1);
        scanf("%f", &arr[i]);
    }

    // storing the largest number to arr[0]
    for (i = 1; i < n; ++i) {
        if (arr[0] < arr[i])
            arr[0] = arr[i];
    }

    printf("Largest element = %.2f", arr[0]);

    return 0;
}

Example 2: how to find max in array

int[] a = new int[] { 20, 30, 50, 4, 71, 100};
		int max = a[0];
		for(int i = 1; i < a.length;i++)
		{
			if(a[i] > max)
			{
				max = a[i];
			}
		}
		
		System.out.println("The Given Array Element is:");
		for(int i = 0; i < a.length;i++)
		{
			System.out.println(a[i]);
		}
		
		System.out.println("From The Array Element Largest Number is:" + max);
