My teacher give me a homework.I'm a kid from thailand
She said if you don't understand you can ask someone else

Given 3 Interger A,B and C it may not ordering but we know as A<B<C

Question
Ordering the Given Number

Input Data
First line Including 3 number, left 1 space each that 3 number must less than 100
Second line Including 3 letter is A,B and C by noft left space this is the ordering if the number

output data
only one line and order as the given input order

Example
input------output
1 5 3 ----->1 3 5
ABC
6 4 2 ------>6 2 4
CAB

i don't know why n=ABC is undeclare

(This is C, right?)

On line 11 you write if (n = ABC), ABC is undeclared (you didn't tell the compiler what ABC is, same for the other permutations).

Also, I think you mean something like if (n == ABC)?

The design has to be reviewed. It's better (and looks better) if you use an array and sort the numbers.
