Easy generic toString() function in C++

In c++ you can make a simple toString() template function that converts primitives to a string.

#include <iostream>
using namespace std;

template<typename T>
string toString(T t) {
    stringstream s;
    s << t;
    return s.str();
}

This will work for any type that defines the << operator for use with streams.

So with this simple one function we have an "int to string" function, a "float to string" function, a "double to string" function, etc...

Using it is of course simple:

int main() {
    string s0 = toString(100);
    string s1 = toString(100.1f);
    string s2 = toString(100.12);
    cout << s0 << " " << s1 << " " << s2 << endl;
    return 0; // Prints out "100 100.1 100.12"
}
