Exercise 3: Write a program that reads 8 floats into an array and then prints out the second, fourth, sixth and eighth members of the array, and the sum of the first, third, fifth and seventh, using pointers to access the members of the array.

#include<stdio.h>
void header()
{
    printf("\t\t\tBuilt and Designed by Arslan Malik\n\n\n");
    printf("\t\t\t    www.CWorldbyAS.blogspot.com");
}
int main()
{
   float a[8];
   float *p;
   int i;
   float sum=0;
   printf("\n\n\n");
   header();
   printf("\n\n\n\n\n");
   system("pause");
   system("cls");
   for(i=0;i<8;i++)
   {
       printf("Enter %d Number : ",i+1);
       scanf("%f",&a[i]);
   }
   system("pause");
   system("cls");
   p=a;
   printf("\t2nd\t4th\t6th\t8th\n\n\n\n");
   for(i=0;i<8;i++)
   {
       if(i%2==0)
       printf("\t%.2f",*(p+i+1));
       i++;
   }
   printf("\n\n\n\n\n");
   system("pause");
   system("cls");
   p=a;
   printf("\t1st\t3rd\t5th\t7th\n\n\n\n");
   for(i=0;i<8;i++)
   {
       if(i%2==0)
       printf("\t%.2f ",*(p+i));
       sum=sum+*(p+i);
       i++;
   }
   printf("\n\n\n\n\t\tSum is %.2f  \n\n\n\n\n\n",sum);
