Question

Define c++ function CalculateYears() that stimulates the population growth and return the year in which female will be greater than or equal to male population if the currently we have 1750000 male at growth rate is 25% and 1500000 female at thegrowth rate is 35%

Answer 1

int CalculateYears()
{
	int result = 0;

	const int maleCount = 1750000;
	const int femaleCount = 1500000;

	int maleCurrentCount   = maleCount;
	int femaleCurrentCount = femaleCount;

	while (femaleCurrentCount < maleCurrentCount)
	{
		++result;

		femaleCurrentCount += (femaleCurrentCount / 100.0 * 35.0);
		maleCurrentCount   += (maleCurrentCount / 100.0 * 25.0);
	}

	return result;
}
