write in one row

[ahoha]

Hi
I'm writing a program to do the following :
it'll write the names, IDs, etc for people in a predefined txt file,
the problem is, I need to write some information in the same row, not in the next one, like:
John 123214
not:

John
123214

in my below code (The last "void printname" , " void printadd") , it'll do it but the second way( note that: its done through menus and sub-menus)

#include<stdio.h>
#include<stdlib.h>
#include <fstream>
#include <string>
#include <iostream>
#include <iomanip>

/* Prototype */
int ShowMainMenu();
int ShowStudMenu();
int ShowStudSubMenu();
int ShowMarkMenu();
int ShowMarkSubMenu();
 
void PrintID();
void PrintSmark();
void PrintFmark();
 
void PrintName();
void PrintAdd();

using namespace std;


int main(void)
{
   int 
      nChoice = 0;
 
   do
   {
      nChoice = ShowMainMenu ();
      switch (nChoice)
      {
         case 1:
         {
            ShowStudMenu ();            
         }
         break;
 
         case 2: 
         {
            ShowMarkMenu ();
         }
         break;
 
         case 7: 
         {
            printf ("Bye Bye\n\n");
         }
         break;
      }
   }
   while (nChoice != 7);
   system ("Terminating Program");
   return 0;

WOW!
really? no one have a clue !

Or maybe it's because your code is broken in ways that extend beyond writing on separate lines. You're including C headers on lines 1 and 2, line 55 almost certainly is wrong, you're mixing C and C++ I/O (cout vs printf and cin vs scanf), you're using C-style strings on lines 218-219 and 234-235, one of those strings in each function is not initialized.

However, as for the issue you mention, you've split writing one line into two functions which may not be called in the correct order. Each function writes a line. You'll likely either need to assure that the functions are called in the write order, or have the actual write happen outside of either function.
