Have a good day!
Hello Here is a C Program to Find the Smallest Element among Array element. Here we use Dynamic Memory Allocation to Set the size of Array. And all other are as usual.

#include<stdio.h>
#include<stdlib.h>
void main()
{
    int *p,n,i,min;
    printf("Enter the total number of elements:- ");
    scanf("%d",&n);
    p = (int *) malloc(sizeof(int) * n);
    printf("Enter the Elements of the Array:- \n");
    for(i=0;i<n;i++)
    {
        scanf("%d",(p+i));
    }
    min=*p;
    for(i=0;i<n;i++)
    {
        if(min>*(p+i))
        {
            min=*(p+i);
        }
    }
    printf("The Minimum ammong the Elements is %d",min);
}


p = (int *) malloc(sizeof(int) * n);
Here memory are allocated and the first memory is assigned to the first element.

#include<stdio.h>
int ffact(int *);
int sqr(int *);

void main()
{
    int a,fact;
    printf("Enter the number:- ");
    scanf("%d",&a);
    fact=ffact(&a);
    printf("Factorial of the given number is %d\n",fact);
    fact=sqr(&a);
    printf("Square of that number is %d",fact);
}
int ffact(int *p)
{
    int i,fact=1;
    if(*p == 0)
        return 1;
    else
    for (i=1;i<=*p;i++)
    {
        fact=i*fact;
    }
    return (fact);
}
int sqr(int *p)
{
    int a;
    a = *p * *p;
    return (a);
}

And after code here is nothing I think I need to describe about.
