Concatenmating an int to a string in C++?

I need to build a string by adding an int value to an existing string.





string s="blah blah";


int num=9;


s=s+num;





doesn't work...





I already tried using itos but I can't get it to work...

Concatenmating an int to a string in C++?
how about sprintf as in





string s="blah blah"


string buffer;


int num=9





sprintf(buffer, "%s%d", s, num);
Reply:You are not initializing string correctly,


string s="whatever";


this is wrong way to initialize a string!!!


right way is,


char s[20]="blah blah";


and i would also like to inform you that there is no need to convert integer to string because string can store numeric and character values both.


To convert string to integer:


num=atoi(s);


To convert string to float:


num=atof(s);
Reply:You have to add like to like.





If you google for "Convert integer to string C++"


you can choose the best way to code this on your system.
Reply:In windows, you can use _itoa to convert an int to a character array. Other systems have something similar.





int num = 9;


string s("blah blah");


char buff[10]; //to hold the output of itoa


::_itoa(num, buff, 10); //10 is base 10.


s += buff;
