char* and int.

i am pretty new to c++ and have ran into a problem.

i have:

int TheInt = 5;
char* TheChar = "WORD";

how can i add the integer to the end of the char*?

so i get the result WORD5

any help would be great, and also if you could explain how it works i'd appreciate it.

Thanks

you wouldn't want to do that. not with pointers.

use strings. they're safe.

Ok.

Now i have:

int TheNumber = 5;
string TheString = "WORD"

How can i get the result WORD5 as stated above, and also convert that result to be used in GetPrivateProfileString().

Any Help Appreciated.

Maybe there're better ways of doing this (adding an
int to a string) but I do it this way and it seems to work fine:

Code:

---

#include <iostream>
#include <cstdlib>
#include <string>

using namespace std;

int main()
{
        int TheInt = 5;
        char buf[20];
        string Mystring = "WORD";
       
        Mystring = Mystring + itoa(TheInt, buf, 10);
       
        cout << Mystring;
       
        return 0;
}

Hi

Thanks for replying again.

I tried that and the conversion works fine.
But the end result needed is "char*" as use the result in GetPrivateProfileString().

I got error:

Code:

---

error C2664: 'GetPrivateProfileStringA' : cannot convert parameter 2 from 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' to 'const
 char *'

thanks

You can also use the stringstream classes:

Code:

---


#include <iostream>
#include <sstream>

void display(const char * c){
        std::cout << c << std::endl;
}


int main(){
        int i(5);
        std::stringstream s("WORD");
        s << i;
        display(s.str().c_str());
}

---

Code:

---

#include <iostream>
#include <sstream>
#include <string>
using namespace std;

int main(void)
{
    int thenumber = 5;
    string thestring = "WORD";
    stringstream ss;
    string str;
   
    ss << thenumber;
    ss >> str;
   
    thestring += str;
   
    cout << thestring << endl;
    system("PAUSE");
    return 0;
}

Thanks to everyone who replied!
Appreciated!

Now working fine
