string stc;
void coba(int n,string &st) 
{ int b; 
string sta,stb; 
if (n==0) st = "HEE"; 
else { b = n%2; 
if (n/2>5) stb = 83+b; 
else stb = 65+b; 
coba(n/2, sta); 
st = sta + stb; } }


And my problem is, how to determine the value of stc if calling coba(35,stc).
Please help me guys.... :(

It's all about formatting. Without it the code is unreadable.

#include <iostream>

using std::string;

string stc;
void coba(int n,string &st) 
{ 
  int b; 
  string sta,stb; 
  
  if (n==0) 
    st = "HEE"; 
  else 
  { 
    b = n%2; 
    if (n/2>5) 
      stb = 83+b; 
    else 
      stb = 65+b; 
      
    coba(n/2, sta); 
    st = sta + stb; 
  } 
}

int main()
{
  coba(35, stc);
  std::cout << stc;
  return 0;
}
