Read numbers

[rjghoul]

Use a one-dimensional array to solve the following problem: Read in 20 numbers between 10
and 100 inclusive. As each number is read, validate it (be sure to be between 10 and 100) and
store it in the array only if it is not a duplicate of a number already read.
After reading all the values, display only the unique values that the user entered.
Sort the array using bubble sort and display the sorted array.

I have one question about this, how do I "read" numbers without using an array?

You can use a variable where you store the number you read. Then you validate the number and, if it's ok, you store it in your array.

then you need 20 variables a,b,c.....
or if you don't call this

std::vector<int>v

an array you can use this.

Actually the first post is a bit strange: the text says

Use a one-dimensional array

but then he says

without using an array

I thought it might be a typing error.

store it in the array only if it is not a duplicate of a number already read.
After reading all the values, display only the unique values that the user entered.

isn't the second sentence redundant?
if only non duplicates are stored,wouldn't the whole array be filled with unique numbers?

the OP cant use <set> for restrictions.
but,

 std::set<int> mySet;
mySet.insert(5);
mySet.insert(8);
mySet.insert(4);
mySet.insert(5);

mySet contains only unique members sorted {4,5,8}

Probably they are at the beginning of a C++ course and have not studied STL yet...
