string substr (size_t pos = 0, size_t len = npos) const; 从pos位置开始后len个字符,[pos,pos+len) ,若没指定len则到字符串结尾 即 [pos,npos) The substring is the portion of the object that starts at character positionposand spanslencharacters (or until the end of the string, whichever...
If the string starts with the pattern prefix, returns substring after the prefix, wrapped in Some. Unlike trim_start_matches, this method removes the prefix exactly once. If the string does not start with prefix, returns None. The pattern can be a &str, char, a slice of chars, or a ...

String in C++ STL (Standard Template Library): In this article, we are going to seehow we can use string as a default datatype? Submitted byRadib Kar, on February 27, 2019 String as datatype In C, we know string basically a character array terminated by\0. Thus to operate with the ...
count - length of the substring that is going to be replaced first, last - range of characters that is going to be replaced str - string to use for replacement pos2 - start of the substring to replace with count2 - number of characters to replace with cstr - pointer to the ch...
In this above syntax, the invoking string is the compared string whose substring to be compared is defined bypos&len. We can compare it with a substring ofstr(a comparing string which is passed in argument) defined bysubpos & sublen. ...
