stick integer to string and char*

[arianmd]

Dear all,
How can add an integer variable to a string and char* variable? for example:
int a = 5;
string St1 = "Book", St2;
char *Ch1 = "Note", Ch2;

St2 = St1 + a --> Book5
Ch2 = Ch1 + a --> Note5

Thanks

You'd have to convert the integer into a string (or character if its a single number).

I would recommend using stringstreams.
http://cplusplus.com/reference/iostream/stringstream/

I.e.

#include <string>
#include <sstream>
#include <iostream>
#include <string.h>

int main()
{
    std::stringstream ss;
    int a = 5;
    std::string st1 = "Book";
    std::string st2 = "";
    char * ch1 = "Note";
    char * ch2 = NULL;

    ss<<st1<<a;
    ss>>st2;

    std::cout<<st2<<std::endl;   

    //clear the stream;
    ss.clear();
    ss.str("");
   
    ss<<ch1<<a;
    ch2 = new char [ss.str().length() + 1];
    strcpy(ch2, ss.str().c_str());

    std::cout<<ch2<<std::endl;
    delete [] ch2;
    return 0;
}

Edit... Read warnis's link and my post was covered there aswell.
