Answer 1

#include <stdio.h>
void fun(int *a, int n)
{
    int t;
    for (int i = 0; i < n-1; i++)
        for (int j = 0; j < n-1-i; j++)
            if (a[j]<a[j+1])
            {
                t = a[i];
                a[i] = a[j];
                a[j] = t;
            }
}
int main()
{
    int a[3];
    int n = 3;
    for (int i = 0; i < 3; i++)
        scanf("%d", &a[i]);
    fun(a, n);
    for (int i = 0; i < n; i++)
        printf("%d ", a[i]);
