C语言经典例题-两个分数相加

# include 

int main()
{
	int numerator1, numerator2;//定义分子
	int denominator1, denominator2;//定义分母
	int numerator = 0;
	int denominator = 0;

	printf("Please input two fractions(Separate with","): ");
	scanf("%d/%d, %d/%d", &numerator1, &denominator1, &numerator2, &denominator2);

	numerator = numerator1 * denominator2 + numerator2 * denominator1;//最后分数的分子
	denominator = denominator1 * denominator2;//最后分数的分母

	printf("result = %d/%dn", numerator, denominator);

	return 0;
}

 最终结果不是最简分数。
