You can use the std::string::find() function to find the position of your string delimiter, then use std::string::substr() to get a token. Example: The find(const string& str, size_t pos = 0) function returns the position of the first occurrence of str in the string, or npos if the string is not found. The substr(size_t pos = 0, size_t n = npos) function returns a substring of the object, … Read more

“2.7.0_bf4fda703454”.split(“_”) gives a list of strings: This splits the string at every underscore. If you want it to stop after the first split, use “2.7.0_bf4fda703454”.split(“_”, 1). If you know for a fact that the string contains an underscore, you can even unpack the LHS and RHS into separate variables: An alternative is to use partition(). … Read more

So for example, an XML parser will take the sequence of characters (or bytes) and convert them into elements, attributes etc. In some cases (particularly compilers) there’s a … Read more

If your string contains exactly one character the simplest way to convert it to a character is probably to call the charAt method:
A context free grammar is a grammar which satisfies certain properties. In computer science, grammars describe languages; specifically, they describe formal languages. A formal language is just a set (mathematical term for a collection of objects) of strings (sequences of symbols… very similar to the programming usage of the word “string”). A simple example of … Read more
