    Put an integer in a string?

    Hey everyone,

    I was working on a project, when I ran into a problem. I've got a string, and an integer, and I need to put the integer into the string as an int. Here's what I mean:

    Code:
    string f;
    int i = 3;
    
    f = "{VKEY " + i + "}"; //I don't think I can use the + symbols
    
    //the value of f should be {VKEY 3}
    How can I do this?

    Code:
    #include <sstream>
    
    std::string f;
    int i = 3;
    std::stringstream sstr;
    
    sstr << "{VKEY " << i << "}";
    
    f = sstr.str();
