Create a class called StringDup. Given a string made up of ONLY letters and digits, determine which character is repeated the most in the string ('A' is different than 'a'). If there is a tie, the character which appears first in the string (from left to right) should be returned....

str_dup() 重复字符串中的字符,例如str_dup("xy", 3) 返回"xyxyxy"。 用法 str_dup(string, times) 参数 string 输入向量。或者是一个字符向量,或者是可强制转换为一个的东西。 times 重复每个字符串的次数。 值 与string /times 长度相同的字符向量。 例子 fruit <- c("apple", "pear", "banana"...

直译:未终止的串 不同的编译器对同类错误的提示并不完全相同,但意思是一样的。对这种错误,有的编译器提示为:invalid data initializer 数据初始化无效。不管它怎么提示,意思未变:引号中的内容不能为空。可以用 10 dup(?)
方法名:dup StringTemplate.dup介绍 [英]Make the 'to' template look exactly like the 'from' template except for the attributes. This is like creating an instance of a class in that the executable code is the same (the template chunks), but the instance data is blank (the attributes). Do...
PWSTR ResUtilDupString( [in] LPCWSTR pszInString ); 参数 [in] pszInString 指向要复制的字符串的指针。 返回值 如果操作成功,该函数将返回指向包含重复字符串的缓冲区的指针。 如果操作失败,该函数将返回 NULL。 有关详细信息,请调用函数 GetLastError。 注解 使用ResUtilDupString 实用工具函数时,使用返回...
count equ $-string buffer db count dup(0) 下面程序段是实现把string中所有字符逆向传送到buffer缓冲区(即将string中第一个字符送到buffer的最后一个单元,sting中最后一字符送到buffer的第一个单元,……)。请把程序中所空缺的指令填上。 mov si,offset buffer-1 ...
