Answer 1

Here is the code in C for the query. call the initialize function to do all the calculation. Initialize the array to 0 at start. then take the user's intent for more values. If the user wants more add the memory spaces using malloc. For every requirement double the memory space for future purposes

#include<stdio.h>
#include<stdlib.h>
int initialize();
int count;
int *a;
int main()
{
   initialize();
   printf("Size of Array is: %d", count*sizeof(int));
   return 0;
}

int initialize()
{
count=0;
   char c;
   int n=0;
   while(1)
   {
       printf("Do you want to enter elements?");
       scanf("%c",&c);
       if(c=='y'||c=='Y')
       {
           n+=1;
           a = (int*)malloc((n*2)*sizeof(int));
           scanf("%d",a[count++]);
       }
       else
           break;
   }
   if(count==0)
       return 0;
   else
       return count;
}
