Arithmetic

Integer division drops the decimal part; use double for exact answers.

What you are building

The task in front of you: What does 11667 % 2 give?.

The editor already holds a working starting point. Do not delete it and start again — read it, change one thing, run it, and watch which check moves. That loop is the whole method.

Why this matters

You are inside the section “Section 1 · First programs” of the C++ Foundations track. Everything in this section builds towards the section project, and this task is one of the pieces that project leans on.

In real work nobody marks your code — it either runs or it does not, and someone is waiting for the result. The checks here are deliberately strict about output, because a program that prints the right thing in the wrong shape fails in the real world too.

The key idea

C++ makes you say what type every value has, and the compiler believes you. That strictness is the point: the error you get at compile time is a bug you did not have to debug at runtime.

Every statement ends in a semicolon, and main() is where the program starts. Read compiler errors from the top: the first one is usually the real one.

Two mistakes to avoid

  • Forgetting std:: or the namespace, then blaming the compiler. If it says "not declared", check the include and the namespace first.
  • Declaring a variable inside an if block and using it after the block ends. The name only exists between the braces that created it.

What the automatic checks look for

The right-hand column runs 1 check every time you press Run code. Nothing is hidden:

  • The output has to contain “out:Total: 35001 Half…”.

Task

What does 11667 % 2 give?

The editor already contains a starting point. Change it until every check passes — the Next task button unlocks when it does.

What you start with 
#include <iostream>
using namespace std;

int main() {
    int months = 3;
    int monthly = 11667;
    cout << "Total: " << months * monthly << endl;
    cout << "Half: " << monthly / 2 << endl;
    cout << "Remainder: " << monthly % 2 << endl;
    return 0;
}

Stuck? The Hint button at the bottom nudges you one step without handing over the answer — that is on purpose: an exercise you copied teaches nothing.
