convert a C++ std::string to the template type you specify

main.cpp

#include <iostream>
#include <string>
#include "sstreamconvert.h"

int main( int argc, char **argv ) { 

    //convert a string to a double
    double D = convert_to <double>("13.37");
    std::cout << "We can convert a string to a double using our neat template code" << std::endl;
    std::cout << "The value of D is: [" << D << "]." << std::endl;
    return 0;
}

Makefile

all:
    g++ -Wall -g -o sstream-convert.x86 main.cpp
clean:
    rm sstream-convert.x86

sstreamconvert.h

#include <sstream>
#include <string>

template <typename T> T convert_to (const std::string &str)
{
    std::istringstream ss(str);
    T num;
    ss >> num;
    return num;
}

Thank you, it is really helpful!
