split up string in c++ code example
Example 1: split a string based on a delimiter in c++
void tokenize(string &str, char delim, vector<string> &out)
{
size_t start;
size_t end = 0;
while ((start = str.find_first_not_of(delim, end)) != string::npos)
{
end = str.find(delim, start);
out.push_back(str.substr(start, end - start));
}
}
int main()
{
string s="a;b;c";
char d=';';
vector<string> a;
tokenize(s,d,a);
for(auto it:a) cout<<it<<" ";
return 0;
}
Example 2: split in c++
std::string s = "scott>=tiger>=mushroom";
std::string delimiter = ">=";
size_t pos = 0;
std::string token;
while ((pos = s.find(delimiter)) != std::string::npos) {
token = s.substr(0, pos);
std::cout << token << std::endl;
s.erase(0, pos + delimiter.length());
}
std::cout << s << std::endl;
