An array of strings-CodePudding

How can I modify to make him calls the constructor? Textbooks code error is no

 
The class s {
Public: 
S () {
* STR='\ 0'; Len=0; 
} 
S (char * PSTR) 
{
Strcpy (STR, PSTR); Len=strlen (PSTR); 
} 
Char * gets () {
return str; 
} 
Int getLen () 
{
Return len. 
} 
S operator + obj (s); 
Private: 
Char STR [100]. 
Int len. 

}; 
S s: : operator + obj (s) 
{
Strcat (STR, obj. STR); 
return str; 
} 
Int main () 
{
S obj1 (" Visual "); 
S obj2 (" c + + "); 
S obj3 (" language "); 
Obj3=obj1 obj2 + + obj3; 
Cout & lt; <"Obj3. STR=" & lt; Cout & lt; <"Obj3. Len=" & lt; }

Cout & lt; <"Obj3. STR=" & lt; Cout & lt; <"Obj3. Len=" & lt; }

S obj1 (" Visual "); This line is changed to obj1=new s (" Visual "); Give it a try, I am also a small white
