C++ Parse Split Delimited String
Posted by admin in C Plus Plus on February 18, 2009
This article teaches you how to parse split delimited string in C++. This is one of the most handful function you can use for delimited string like CSV – comma separated value.
#include <string>
#include <vector>
#include <functional>
#include <iostream>
using namespace std;
void split(const string& s, char c,
vector<string>& v) {
string::size_type i = 0;
string::size_type j = s.find(c);
while (j != string::npos) {
v.push_back(s.substr(i, j-i));
i = ++j;
j = s.find(c, j);
if (j == string::npos)
v.push_back(s.substr(i, s.length( )));
}
}
int main( ) {
vector<string> v;
string s = "Account Name|Address 1|Address 2|City";
split(s, '|', v);
for (int i = 0; i < v.size( ); ++i) {
cout << v[i] << '\n';
}
}
