#include<stdio.h>
#include<stdlib.h>

int main() {
int n, *arr, i, min, max, tmin, tmax, start=2;
printf("How many elements:");
scanf("%d", &n);
arr = (int *) malloc(sizeof(int) * n);

printf("Enter %d Elements:", n);
for (i=0; i<n; i++)
scanf("%d", &arr[i]);

if(arr[0] < arr[1]) { // 1 comparison
min = arr[0];
max = arr[1];
} else {
min = arr[1];
max = arr[0];
}

tmin = min;
tmax = max;

if(n%2) {
if(arr[2] < min)
min = arr[2];
if(arr[2] > max)
max = arr[2];
start = 3;
}


for(i=start; i < n; i+=2) //
(n-2)/2 elements
{
if(arr[i] < arr[i+1]) { // 1 comparison
min = arr[i];
max = arr[i+1];
} else {
min = arr[i+1];
max = arr[i];
}

if(tmin < min) // +1
min = tmin;
if(tmax > max) // +1 = 3
max = tmax; // Total
comparisons = 3(n-2)/2
}

printf("Min: %d \nMax: %d\n", min, max);

}



Note: This gives a slightly better running time.
