I've got the following code:
std::string str = "abc def,ghi";
std::stringstream ss(str);
string token;
while (ss >> token)
{
printf("%s\n", token.c_str());
}
The output is:
abc
def,ghi
So the stringstream::>> operator can separate strings by space but not by comma. Is there anyway to modify the above code so that I can get the following result?
input: "abc,def,ghi"
output:
abc
def
ghi
This question is related to
c++
tokenize
stringstream
#include <iostream>
#include <sstream>
std::string input = "abc,def,ghi";
std::istringstream ss(input);
std::string token;
while(std::getline(ss, token, ',')) {
std::cout << token << '\n';
}
abc
def
ghi
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main()
{
std::string input = "abc,def, ghi";
std::istringstream ss(input);
std::string token;
size_t pos=-1;
while(ss>>token) {
while ((pos=token.rfind(',')) != std::string::npos) {
token.erase(pos, 1);
}
std::cout << token << '\n';
}
}
