Nested if

Read first Task 13

Nested decisions handle a second question inside the first.

Definition and example

Nested if is the focus of this lesson. Nested decisions handle a second question inside the first. The task asks you to apply that idea in a small example: A fee of 9000 against a monthly fee of 11667 is…. Before you run the code, predict what should happen. Then Inspect the program output and the compiler message if it fails and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.

// TASK nested-if-03: A fee of 9000 against a monthly fee of 11667 is…
// STEPS: Read the explanation. Change one relevant line at a time, then run the code and compare the result with the check on the right.
#include <iostream>
#include <string>
using namespace std;

int main() {
    int fee_paid = 9000;
    int monthly_fee = 11667;
    string status;

    if (fee_paid >= monthly_fee) {
        status = "full";
    } else if (fee_paid > 0) {
        status = "TODO";
    } else {
        status = "unpaid";
    }
    cout << status << endl;
    return 0;
}
