答案:cstring类的成员函数trimRight和trimLeft的功能是去除字符串两端的特定字符。解释:在编程中,处理字符串时经常会遇到需要清理或格式化字符串的情况。在C++的字符串处理类cstring中,成员函数trimRight和trimLeft就是为了满足这种需求而设计的。trimRight函数的功能:trimRight函数的主要作用是去除字符串末尾...
CString类中的TrimRight和TrimLeft是两个用于处理字符串的成员函数,它们的主要功能是移除字符串两端的特定字符或字符序列。TrimLeft函数的工作原理是从给定的CString对象a的起始位置开始,逐个检查字符。如果遇到的字符存在于另一个字符串b中,它会从a中移除该字符,直到找到一个不在b中的字符或者到达a的开...
public string TrimEnd (params char[]? trimChars); 参数 trimChars Char[] 要删除或 null的Unicode 字符数组。 返回 String 在trimChars 参数中出现的所有字符之后保留的字符串将从当前字符串的末尾删除。 如果 trimCharsnull 或空数组,则会删除 Unicode 空格字符。 如果当前实例中无法剪裁任何字符,该方法...

假设有CString a和b a.TrimLeft(b)的作用:从a的第一字符开始往后遍历,如果发现某个字符出现在b中,就从a删除,直到某个字符没有在b中出现或者遇到a的结尾。a trimleft # =a a## trimleft # = a TrimRight就是从a的最后一个字符开始往前遍历,规则一样 Trim就是两边遍历,也就是分别执行一次...
