Question

Which of the following require saving all the values from standard input (in an array, say), and which could be implemented as a filter using only a fixed number of variables? For each, the input comes from standard input and consists of N real numbers between 0 and 1.

Print the maximum and minimum numbers.
Print the kth smallest value.
Print the sum of the squares of the numbers.
Print the average of the N numbers.
Print the percentage of numbers greater than the average.
Print the N numbers in increasing order.
Print the N numbers in random order.

Explanation / Answer

please rate - thanks

any questions ask

any better --or do you need code for all of them? that is not a trivial task

Print the maximum and minimum numbers. --can be calculated as number is input -no array

for(i=1;i<=n;i++)
       {cin>>n;

       if(n>high)

              high=n;
      if(n<low)

             low=n;

     }

Print the kth smallest value. --need to save-array

but to do this 1, you need all the numbers(at least k of them), in order to compare them

Print the sum of the squares of the numbers. --can be calculated as number is input -no array
Print the average of the N numbers. --can be calculated as number is input -no array
Print the percentage of numbers greater than the average. --need to save-array
Print the N numbers in increasing order. --need to save-array
Print the N numbers in random order. --need to save-array
