Thats all!

    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.

    }
}

And I think you understand this code.

}

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