In this article we will see 2 techniques to split a std::string in C++ and return the result in std::vector<std::string> i.e.
- Splitting a std::string using a char as delimiter.
- Splitting a std::string using an another std::string as delimiter.
How to Split a std::string using a char as delimiter:
In this article I will show you a way to implement a switch on strings using pure standard C. I can't give you a solution to do exactly what you can do in C#. The Standard Template Library (STL), part of the ANSI/ISO C Standard, offers everything needed to get really close to the C# sample. The solution is very. A sub string is a string that is created from, or is included in, another string. C and C Builder allow you to find a sub string in an original string, to get the position of a sub string in a string, etc. With a string, you can create a new string retrieved from the original. Split string into tokens A sequence of calls to this function split str into tokens, which are sequences of contiguous characters separated by any of the characters that are part of delimiters. On a first call, the function expects a C string as argument for str, whose first character is used as the starting location to scan for tokens.
In this we will convert the passed string into a stringstream and from that string stream we will fetch each word using getline method,
But wait a minute, above function splits a string by a character delimiter but what if I want to split it based on another string,
like if first string is “Lets split this line using split functions” then on splitting it with “split” delimiter the result should be,
“Lets”
“this line using”
“functions”
To achieve this we have to write an another split function with std::string as delimiter i.e.
How to split a string by another string as delimiter:
C String Split On Char
In the above code we will search for the delimiters in the passed string and fetch the sub strings in between them.
