要获取“ArC”的意思，您可以使用在线词典API来查询。以下是使用Python编写的示例代码：

import requests

def get_meaning(word):
    url = f'https://api.dictionaryapi.dev/api/v2/entries/en/{word}'
    response = requests.get(url)
    data = response.json()
    
    # 提取词义
    meanings = []
    for entry in data:
        for meaning in entry['meanings']:
            meanings.append(meaning['definitions'][0]['definition'])
    
    return meanings

word = 'ArC'
meanings = get_meaning(word)
if meanings:
    print(f"The meaning(s) of '{word}' is/are:")
    for meaning in meanings:
        print(meaning)
else:
    print(f"No meaning found for '{word}'.")

请确保您已经安装了requests库，可以使用以下命令进行安装：

pip install requests

以上代码将使用在线词典API查询ArC的意思，并将结果打印出来。请注意，由于ArC不是一个常见的单词，所以可能无法找到对应的意思。
