Splitting a string in C++
In PHP, the explode()
function will take a string and chop it up into an array separating each element by a specified delimiter.
Is there an equivalent function in C++?
Here's a simple example implementation:
#include <string>
#include <vector>
#include <sstream>
#include <utility>
std::vector<std::string> explode(std::string const & s, char delim)
{
std::vector<std::string> result;
std::istringstream iss(s);
for (std::string token; std::getline(iss, token, delim); )
{
result.push_back(std::move(token));
}
return result;
}
Usage:
auto v = explode("hello world foo bar", ' ');
Note: @Jerry's idea of writing to an output iterator is more idiomatic for C++. In fact, you can provide both; an output-iterator template and a wrapper that produces a vector, for maximum flexibility.
Note 2: If you want to skip empty tokens, add if (!token.empty())
.
