- I have a problem spliting a string in to substrings and insert dots and colons in fixed possitions. I get input from a file deliminated by comas row by row. One of the tokens contain string '2526' which I need to split in to 2 separated strings and manipulate it at the same they need to look like str1 = '2005.09.13' and str2 = '23:25:26' Basically the String is Date and Time in one.
- Split is used to break a delimited string into substrings. You can use either a character array or a string array to specify zero or more delimiting characters or strings. If no delimiting characters are specified, the string is split at white-space characters.
- 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.
C Split String Into Words

A C solution, since it involves using C arrays. Another problem is its low-level nature: the user must send a pointer to help strtok. In this example I have derived a class splitstring from string. If you have a splitstring and you want to use it as a string, you can, because it is one. But if you need to split the string, you can split it too.

There is no standard way of trimming a
string
, but it’s possible to implement using the methods in the string
class:- Left trim: Use
find_first_not_of()
to find the characters to erase - Right trim: Use
find_first_of()
to find the characters to erase - Trim: Do a right trim followed by a left trim (or vice-versa)
C Split String On Spaces
Use
erase()
to actually erase the characters.Here is my implementation. It defaults to trimming whitespace characters but you can specify any string of characters as the second argument.
Here’s a test program:
And here’s the valgrind output:
