bool operator!= (const char *Cstr, String &s)
 Global Cstr != String operator, where Cstr is a "C" string.

bool operator<= (const char *Cstr, String &s)
 Cstr <= s: however, we must use the comparision s to Cstr.

 Cstr >= s: however, we must use the comparision s to Cstr.

bool operator< (const char *Cstr, String &s)
 Cstr < s: however, we must use the comparision s to Cstr.

bool operator> (const char *Cstr, String &s)
 Cstr > s: however, we must use the comparision s to Cstr.

bool operator!= (  const char *  Cstr,
String &  s
) 
 

Global Cstr != String operator, where Cstr is a "C" string.

Definition at line 459 of file String.C. 

00460 {
00461   return (s != Cstr);
00462 } // operator !=

String operator+ (  const char  ch,
String &  s
) 
 

Global operator +: Concatenate a character and a String object. 


     String Str("ab");
     String a;

     a = 'c' + Str

Here, "a" will contain "abc"

Definition at line 434 of file String.C. 

00435 {
00436   String tmp;
00437 
00438   tmp = ch;
00439   tmp += s;
00440 
00441   return tmp;
00442 } // global operator +

String operator+ (  const char *  Cstr,
String &  s
) 
 

Global operator +: "abcd" + String(" efgh").

This operator supports an operation like "abcd" + String(" efgh"). The result of this operator would be a String object containing "abcd efgh".

Definition at line 409 of file String.C. 

00410 {
00411   String tmp;
00412   if (Cstr != 0) {
00413     tmp = Cstr;
00414   }
00415   
00416   tmp += s;
00417   return tmp;
00418 } // global operator +

bool operator< (  const char *  Cstr,
String &  s
) 
 

Cstr < s: however, we must use the comparision s to Cstr.

So this expression is true if s > Cstr.

Definition at line 495 of file String.C. 

00496 {
00497   return (s > Cstr);
00498 } // global operator <

bool operator<= (  const char *  Cstr,
String &  s
) 
 

Cstr <= s: however, we must use the comparision s to Cstr.

So this expression is true if s >= Cstr.

Definition at line 471 of file String.C. 

00472 {
00473   return (s >= Cstr);
00474 } // global operator <=

bool operator== (  const char *  Cstr,
String &  s
) 
 

Global Cstr == String operator, where Cstr is a "C" string.

Definition at line 449 of file String.C. 

00450 {
00451   return (s == Cstr);
00452 } // global operator ==

bool operator> (  const char *  Cstr,
String &  s
) 
 

Cstr > s: however, we must use the comparision s to Cstr.

So this expression is true if s < Cstr.

Definition at line 507 of file String.C. 

00508 {
00509   return (s < Cstr);
00510 } // global operator >

bool operator>= (  const char *  Cstr,
String &  s
) 
 

Cstr >= s: however, we must use the comparision s to Cstr.

So this expression is true if s <= Cstr.

Definition at line 483 of file String.C. 

00484 {
00485   return (s <= Cstr);
00486 } // global operator >=
