    long long int population = basePopulation;
    long long int increase = 0;

    double growthRate = 0.0113f;
    int sample = 10;


    printf("\n*** Population projection for %d years ***\n", sample);

    printf("Year\t\tPopulation\t\tIncrease\n");

    for (int i = 1; i <= sample; i++) {
        increase = population * growthRate;

        printf("%d\t\t%lld\t\t%lld%s\n", i, population, increase,(population > basePopulation * 2) ? " - Population Doubled" : "");

        population += increase;/* w  ww .  j av a  2 s. c om*/
