You probably need to give more information, because this works for me.

 

Visual Studio 2010 Ultimate.

#include <cstdio>
using namespace std;
 
int main(int argc, char*argv[]) {
  char start[2000];
  char browser[] = "internetexplorer.exe";
  char site[] = "fearleass-assassins.com";
  char temp[] = "yes";
  char min[] = "no";
  sprintf(start,"START %s %s?temp=%s&min=%s",browser,site,temp,min);
  printf("%s", start);
  getchar();
  return 0;
}

 

And you probably need to align it yourself, cause IP.boards is f#$chikng this up, but it works. Are you using strings?

And also under Linux btw.

no char's

No problem. You just discovered why strings suck.

 

 

Anyway, the easy solution is to not use sprintf. Every string can be constructed using "+". E.g.

 

 

 

 

 

#include <string>
#include <iostream>
using namespace std;
int main(int argc, char*argv[]) {
string start;
string browser = "internetexplorer.exe";
string site = "fearleass-assassins.com";
string temp = "yes";
int min = -3;
//sprintf(start,"START %s %s?temp=%s&min=%s",browser,site,temp,min);
start = "START " + browser + " " + site + "?temp=" + temp + "&" + to_string((long double)min);
cout << start << endl;
getchar();
return 0;
}

 

Of course you get problems once you discover that an integer cannot be represented as a string (e.g string start = "a" + 1), but you can solve that as in the example code.

k thanks rolf gonna try that tomorrow and let you know how it works out

after thinking this hard we realized that since we started the browser on cmd line and ofc command line didnot understand '&' coz its command on it and we needed it to go thru as only symbol so it worked when we did this ^& and we used windows so i think '&' work's on linux as symbol only but yeah thanks for effort rolf
