is there a way to include a integer variable in a string?

[momo12]

Hi,

is there a way to include a integer variable in a string?

Example:

string A;
int N;

A = "image N" //where N will be replaced with what is in the integer variable N.

//like when we do printf("inage %d", N) but storing the string in the variable without printing.

Thanks

It is undefined to use sprintf on a std::string ... use stringstream

Example:

#include <string>
#include <iostream>
#include <sstream>

using namespace std;

template <typename T1 , typename T2>
T2 Convert(const T1 & t1)
{
    T2 t2 = T2();

    std::stringstream ss;  // include <sstream>

    ss << t1;

    ss >> t2;

    return t2;
}


int main(int argc , char* argv[])
{
    int n = 10;

    string s = "image ";

    s += Convert<int,string>(n);

    cout << s << "\n";

    return 0;
}

You're right, I should have read the post more carefully. I thought he was asking about a char array.
