在(原創) 如何将字符串前后的空白去除? (使用string.find_first_not_of, string.find_last_not_of) (C/C++) (STL)中已经可顺利将字符串前后的空白去除,且程序相当的精简,在此用另外一种方式达到此要求,且可同时将whitespace去除,并且使用template写法。
string a=s.substr(0,4); //获得字符串s中 从第0位开始的长度为4的字符串 5. 字符串搜索 where = str1.find(str2); where = str1.find(str2,pos1); pos1是从str1的第几位开始。 where = str1.rfind(str2); 从后往前搜。 6. 插入字符串 ...
