Explanation / Answer

Initialize size to 0;

Initialize Numlist to 1000;

Initialize avg to 0.0;

Initialize max to 100;

Initialize min to 11;

Initialize m to 71.47;

Initialize s to 20.98;

Open input.txt file

If the file opening is failed

Print cannot open input.txt

Exitfailure

For each count equals to zero and count less than numlist

Infile equals to list of count

If not in file

Break.

Size of standarad deviation array to 100

Infile equal to p

While infile not equal to end of the file and size less than number list

Standard deviation of array size equals to p

Size is incremented by 1

And infile equal to p

Call function sum with the arguments Standard deviation,size

Assign sum to totsum

Call function mean with the arguments Standard deviation,size

And assign mean to average

Print Standard deviation

Print mean

Print maximum score

Print minimum score

Print range

Print grade

System pause

Return 0

// Call function sum

Initialize sum equals to 0

For each p equals to zero and p less than size

Add the sum to vector array of p

Return the sum

// Call function mean

Initialize sum equals to 0

Initialize mean equals to 0

For each a equals to zero and a less than size

Add the mean to vector array of size

If the size equals to 0

Then

Mean equals to 0

Else

Mean equals to mean divided by size

Return mean.

// call function deviation

U equals to (sum-mean)2

S equals to square root of u divided by p

Return s
