1.3 string insert, replace, erase 了解了string 的操作符,查找函数和substr,其实就已经了解了string的80%的操作了。insert函数, replace函数和erase函数在使用起来相对简单。下面以一个例子来说明其应用。 string只是提供了按照位置和区间的replace函数,而不能用一个string字串来替换指定string中的另一个字串。这里写...
Method 1: Use std::replace() 1 2 3 4 5 6 7 8 9 10 #include <iostream> #include <string> #include <algorithm> int main() { std::string str("Quick+brown+fox"); std::replace(str.begin(), str.end(), '+', ' '); std::cout << str << "\n"; } Method 2: Use std::...
string(“hello”) + string(“world”) == string(“helloworld”) string 符合 vector 的接口,例如 begin/end/size/resize…… string 有一系列成员函数,例如 find/replace/substr…… string 可以通过 s.c_str() 重新转换回古板的 const char *。 string 在离开作用域时自动释放内存 (RAII),不用手动 free。
One of my low-priority todo items is to replace character arrays with std::string to help ensure that there are no overflows we have overlooked. I took a look through the code, 99% of the use of char arrays is using them as byte buffers for things like images, or fixed size data s...
<string> int main (){ std::string s0 ("Initial string");// constructors used in the same order as described above:std::string s1;std::string s2 (s0);std::string s3 (s0, 8, 3);std::string s4 ("A character sequence");std::string s5 ("Another character sequence", 12);
std::vector<std::string> words = boost::assign::list_of("words")( "\"some\"")( "of which")( "\"might\"")("be quoted"); 我正在寻找删除引号的最有效方法。这是我的尝试 for(std::vector<std::string>::iterator pos = words.begin(); pos != words.end(); ++pos) ...
