Straight Min Max Algorithm

Language: C

#include <stdio.h>
void arr_min_max(int arr[], int size, int *min, int *max) { 
    *min = *max = arr[0]; 
    for (int i = 1; i < size; i++) {
        if (arr[i] > *max) {
            *max = arr[i];
        } else if (arr[i] < *min) {
            *min = arr[i];
        }
    }
}
int main() {
    int n;
    printf("Enter size of array : ");
    scanf("%d",&n);
    int arr[n];
    printf("Enter the array: \n"); 
    for(int i =0;i < n;i++)
    scanf("%d",&arr[i]); 
    int min, max;
    arr_min_max(arr,n, &min, &max);
    printf("Minimum value: %d\n", min);
    printf("Maximum value: %d\n", max);
    return 0;
}

Output:

Enter size of array : 5
Enter the array:
4 7 3 9 10
Minimum value: 3
Maximum value: 10
