Question

I have some integers, let’s say one two and three. I wish to create a string such as

char* example = "There are " + one + " bottles of water on " + 
    two + " shelves in room number " + three + "\n".`  

This doesn’t work in C/C++. How can I store that type of value in a char*?

Answer 1

C++ isn’t VB. But you have numerous options.

stringstream:

#include <sstream>
#include <string>

stringstream ss;
ss<< "There are " << one << " bottles of water on " << two << " shelves in room number " << three;
string s = ss.str();

boost/format:

#include <boost/format.hpp>
#include <string>

string s = (boost::format("There are %1% bottles on %2% shelves in room number %3%")%one%two%three).str();

old-school (hacky, unsafe, bad, dont do it)

char buffer[1024] = {};
sprintf(buffer, "There are %d bottles on %d shelves in room number %d", one, two, three);
