编写程序，根据身高和体重计算BMI值，同时输出国际和国内BMI指标建议值所确定的指标分类信息

编写一个计算BMI（身体质量指数）并根据标准分类的简单程序可以按照以下步骤进行。这里以Python为例：

def calculate_bmi(height_cm, weight_kg):
    height_m = height_cm / 100.0  # 转换为米
    bmi = weight_kg / (height_m ** 2)
    return bmi

def classify_bmi(bmi):
    if bmi < 18.5:
        category = "过轻"
    elif 18.5 <= bmi < 24:
        category = "正常"
    elif 24 <= bmi < 28:
        category = "超重"
    else:
        category = "肥胖"

    return bmi, category

# 输入身高和体重
height_cm = float(input("请输入您的身高（厘米）："))
weight_kg = float(input("请输入您的体重（千克）："))

# 计算BMI
bmi = calculate_bmi(height_cm, weight_kg)

# 分类
international_classification = classify_bmi(bmi)

# 输出结果
print(f"您的BMI值是: {bmi}")
print(f"国际分类: {'健康' if international_classification[1] == '正常' else international_classification[1]}")
print(f"国内分类（中国成年人参考）: {'偏低' if international_classification[1] == '过轻' else international_classification[1]}")
