I have a string \"stack+ovrflow*newyork;\" i have to split this stack,overflow,newyork
any idea??
First and foremost if available, I would always use boost::tokenizer for this kind of task (see and upvote the great answers below)
Without access to boost, you have a couple of options:
You can use C++ std::strings and parse them using a stringstream and getline (safest way)
std::string str = "stack+overflow*newyork;";
std::istringstream stream(str);
std::string tok1;
std::string tok2;
std::string tok3;
std::getline(stream, tok1, '+');
std::getline(stream, tok2, '*');
std::getline(stream, tok3, ';');
std::cout << tok1 << "," << tok2 << "," << tok3 << std::endl
Or you can use one of the strtok family of functions (see Naveen's answer for the unicode agnostic version; see xtofls comments below for warnings about thread safety), if you are comfortable with char pointers
char str[30];
strncpy(str, "stack+overflow*newyork;", 30);
// point to the delimeters
char* result1 = strtok(str, "+");
char* result2 = strtok(str, "*");
char* result3 = strtok(str, ";");
// replace these with commas
if (result1 != NULL)
{
*result1 = ',';
}
if (result2 != NULL)
{
*result2 = ',';
}
// output the result
printf(str);
