    Smile Void Help ()

    Here is the code i have so far i need to define the elements using void

    Code:
    # include <iostream>
    
    using namespace std;
    void clrscr (); //Prototype
    void pause (); //prototype
    void skipBlanks (); // prototype
    int main ()
    
    {
    cout << "Calling function Clear Screen\n";
    clrscr();
    
    cout << "Calling function pause\n";;
    pause();
    }
    
      char ch;
      while(ch=cin.peek()==' ' || ch=='\t' 
            || ch=='\n' || ch=='\r') cin.get();} 
     
      string title, id; 
      double price; 
      {
      cout << "Enter your student ID: "; 
      cin >> id; 
      cout << "Enter a book title: ";
      cin >> title;
    
    system ("pause");}
    and write the function getblanks ();
    prototyped by void getBlanks ()

    i think that i have done the first part okay after trying to complie the code i hav eincluded i get the following errors

    18 expected unqualified-id before "while"
    18 expected `,' or `;' before "while"
    19 expected declaration before '}' token

    Any help or fixed code would be greatly appriciated

    Indentation is seriously messed up. You need to fix it.
    Then you realize that pretty much all code is outside the main function. Outside any function. This isn't allowed. The code must be inside a function.

    Sipher ??

    Elsysia yes i relaised this although i think the code supplied is wrong any way to write it using the void statements and the char ch which i was told is to be used as a check for whitespace/newline characters

    Code:
    while(ch=cin.peek()==' '
    precedence problem?

    it maybe a precedence issue what would be nice is if you could create a function that skips blanks using the void skipBlanks as a prototype and calling it with the skipBlanks () which runs a check for newline or whitespace characters etc which maybe the code is used as a guide what to check for.

    Any help would be greatly appriciated by changing the programs structure

    i get errors on line 25 - 29

    28 expected constructor, destructor, or type conversion before '>>' token
    all stem from the cout statement


    Code:
    cout << "Calling function Clear Screen\n";
    clrscr();
    
    cout << "Calling function pause\n";;
    pause();
    void pause ();
    void clrscr ();
    
      char ch;
      while(ch==cin.peek()==' ' || ch=='\t' 
            || ch=='\n' || ch=='\r') cin.get();} 
     
      string title, id; 
      double price; 
    
      cout << "Enter your student ID: "; 
      cin >> id; 
      cout << "Enter a book title: ";
      cin >> title;
    }
    now this has line 10 to 29 i have skipped the prototypes and system ('pause') and kept it all in main () is there any way to even use the function provided i would be happy with a rewrite or similar even if it is on that singular function thanks.
