How to convert an int to string

Question

I have the following c++ function and I would like to know how to convert an int to a string for the else clause of the if statement.

string afficherValeurNominal(int val)
{
    string valAffiche = "";
    if (val == 11) // carte j
    {
        valAffiche = "V";
    }
    else if (val == 12) // carte Q
    {
        valAffiche = "D";
    }
    else if (val == 13) // carte k
    {
        valAffiche = "R";
    }
    else
    {
        valAffiche = val;
    }
    return valAffiche;
}

Why don't you switch (val) instead of repeated else if?

Use to_string.

valAffiche = std::to_string(val);

int a = 22;
stringstream ss;
ss << a;
string str = ss.str();

Use boost library.

int i = 42;
std::string str = boost::lexical_cast<std::string>(i);
