Furthermore, how does split work in C#?

What are delimiters in C?

A delimiter is one or more characters thatseparate text strings. Common delimiters are commas (,),semicolon (;), quotes ( ", ' ), braces ({}), pipes (|), or slashes( / ). When a program stores sequential or tabular data, itdelimits each item of data with a predefinedcharacter.

What is Strtok in C?

The strtok function is used to tokenize a stringand thus separates it into multiple strings divided by a delimiter.All the next calls with the first argument being NULL use thestring passed at the first call and return the next substring.

What does Strtok return?

Put another way: the tokens returned bystrtok() are always nonempty strings. Thus, for example,given the string "aaa;;bbb,", successive calls to strtok()that specify the delimiter string ";," would return thestrings "aaa" and "bbb", and then a null pointer. Thestrtok_r() function is a reentrant versionstrtok().
