Convert integer to string

[Maurader]

How do i convert an integer to a string??

actually, i need to do

string line;

line = "G" + getIntVal() + getStringVal();
where getIntVal returns an integer and getStringVa() retrns a string

Thanks!

#include <stdio.h>
...
sprintf ( line, &quot;G%d%s&quot;, getIntVal ( ), getStringVal ( ));

error C2664: 'sprintf' : cannot convert parameter 1 from 'const char *' to 'char *'

thx! doh! still doesn't work!


C:\ExtendPaths\NCParser.cpp(243) : error C2440: 'type cast' : cannot convert from 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' to 'char *'

you can use one of this codes:

#include<stdio.h>
.....
...
char buffer[15];
int iValue;
sprintf( buffer,&quot;%d&quot;,iValue );

or

#include<stdlib.h>
.....
...
char buffer[15];
int iValue;
_itoa( iValue, buffer, 10 );

sprintf works with char arrays not strings.
sprintf( char * , char *format , ... );

string str

sprintf( str.c_str , &quot;%d&quot; , value ); dl_harmon@yahoo.com

Use the advantages of C++.

#include <sstream>

ostringstream ostr;

int int_var;
string str_var;

ostr << &quot;G&quot; << int_var << str_var;
cout << ostr.str();

// you can access the string as a char * string too
char *v = ostr.str().c_str();
