Aug 08, 2025 am 02:36 AM檢查std::map中鍵是否存在的方法有三種:1.使用find(),推薦方式,時(shí)間複雜度O(logn),不修改map,高效安全;2.使用count(),代碼簡(jiǎn)潔但性能略低於find(),適合對(duì)性能不敏感的場(chǎng)景;3.使用contains(),C 20引入,語(yǔ)義清晰且性能良好,是現(xiàn)代C 的首選;注意避免使用operator[]判斷存在性,因其會(huì)在鍵不存在時(shí)插入默認(rèn)值,導(dǎo)致意外行為;總結(jié):C 20及以上用contains(),舊版本優(yōu)先用find(),簡(jiǎn)單場(chǎng)景可用count()。
