And it comes with several interesting features like, amongst others, using a substring as delimiter. Ranges should be included in C20, so we can hope to be able to use this feature easily in a couple of years. So, how do I split my string? If you have access to boost, then by all means do Solution 2. Or you can consider rolling out your own. Strtok accepts two strings - the first one is the string to split, the second one is a string containing all delimiters. In this case there is only one delimiter. Strtok returns a pointer to the character of next token. So the first time it is called, it will point to the first word. Char.ptr = strtok (str, delim). The String.Split method creates an array of substrings by splitting the input string based on one or more delimiters. This method is often the easiest way to separate a string on word boundaries. It's also used to split strings on other specific characters or strings.
In this article we will see 2 techniques to split a std::string in C++ and return the result in std::vector i.e.
Split String C Builder For Mac Os
- 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 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:
- Splitting a std::string using a char as delimiter.
- Splitting a std::string using an another std::string as delimiter.

In the above code we will search for the delimiters in the passed string and fetch the sub strings in between them.
