current_maximum = user_number ;You might want to check out where the book lays out each of the types of loops. In the case of a plain while loop, you have something like:
while(stmtA) stmtBdo
stmtA
while(stmtB);The loop exits when the condition in the while is falsified. Every time you get to "the end" of the loop, that condition is tested. If it is true, the loop body is executed again. If it is false, the loop exits. No need for a break at all.
I hope so.
First, you need a format specifier to print the variable. I added a new line as well.
