google.cpp

#include <iostream>
#include <string>
using namespace std;

// Google Search C++ program
// g++ -o google google.cpp
// ./google rodrigo alves github | xargs open
// sudo mv google /usr/bin

int main (int argc, char *argv[])
{
    int i = 1;
    string url =  "https://www.google.com/search?q=";

    for (; i < argc; i++) {
        url = url + string(argv[i]);
        if (i != argc-1) url = url + string("+");
    }

    cout << url << endl;
    string op = string("open ").append(url);
    system(op.c_str());
    return 0;
}

is this platform independent ?

@shyed2001 no

Here is a cross platform example to open URL

#if defined(WIN32) || defined(_WIN32) || defined(__WIN32__) || defined(__NT__)
#define SystemOpenURL(url) system("start " url);
#elif __APPLE__
#define SystemOpenURL(url) system("open " url);
#elif __linux__
#define SystemOpenURL(url) system("xdg-open" url);
#else
#error "Unknown compiler"
#endif
