string format

I have to create some strings in the way cout works independent of data types.Is there any way to write the output to some char buffer or CString in a way similar to cout.

int n=25;
float f=5.11;
char r ='A';

cout<<"my age is = " <<n << "my height is = "<< f << "my grade is = " <<r;





So i have to create such a string and then use message box and show that. I dont know how to write such formatted strings to some buffer...

Any help is appreciated.

Thanks

CString::Format allows sprintf type of formatting ...


int n=25;
float f=5.11;
char r ='A';
//
CString str;
str.Format("my age is = %d , my height is = %f , my grade is = %c",n,f,r);
MessageBox(str);

hi

I use sprintf now. But for that i should know the data type, to put all that %d %f etc.. which is not known to me or will be known at runtime.

thanks

Use the standard STL stringstream...

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

using std::cout;
using std::endl;
using std::string;
using std::stringstream;

int main()
{
int iInt = 25;
float fFloat = 5.11;
char cChar = 'A';
stringstream strsStream;

strsStream << "My age is = " << iInt << ", my height is = " << fFloat << ", my grade is = " << cChar;

// You can now use the stringstream itself
cout << strsStream.str() << endl;

// Or copy its content back to a string
string strString = strsStream.str();
cout << strString << endl;

return 0;
}
