在这个例子中,str.find("world") 用于找到子串 "world" 的位置,然后 str.replace(pos, 5, "C++") 用于从该位置开始替换长度为 5 的子串为 "C++"。 替换所有匹配的子串: 如果你想要替换字符串中所有匹配的子串,可以使用一个循环或者标准库算法(如 std::string::replace_all(C++20 引入))。在C++20之前...
boost::replace_all(myString, "/", "\\/"); std::string result = boost::replace_all_copy(myString, "/", "\\/"); 和其他特殊角色替换 6投票 。在这种情况下,使用Ildjarn给出的 \\实现将很烦人(您需要几次替换同一字符串)。 在我看来,有很多弦处理的案例,没有任何明确的方法可以击败。但是...

The ETL is not designed to completely replace the STL, but to complement it. Its design objective covers the following areas. • Create a set of containers where the size or maximum size is determined at compile-time. • These containers should be largely equivalent to those supplied in ...
