Convert a string variable in enum variable in c++ - c++

Question

I need your help please especially to know can I convert a string Variable in an enum variable.
Here is my code:
deco_fill.h
#include <iostream>
using namespace std;
#include <string.h>
class A{
class B{
public:
enum tStrict{
"ST_UNKNOWN"=-1;
"ST_USE"=0;
"ST_DEL"=1;
}
public:
tStrict mType;
void setStrict(tStrict& newStrict ){
return mType=newStrict;
}
}
}
test.h
#include <iostream>
using namespace std;
#include <string.h>
#include <deco_fill.h>
class C
{
public:
A::B::tStrict CnvStrToEnum(const string& str); //This method will return a tStrict type
}
test.cpp
#include <iostream>
using namespace std;
#include <string.h>
#include <test.h>
#include <deco_fill.h>
A::B::tStrict C::CnvStrToEnum(const string& str)
{
if (str=="ST_USE")
return ST_USE;
else if (str=="ST_DEL")
return ST_DEL;
else
return ST_UNKNOWN;
}
test_set.cpp
#include <iostream>
using namespace std;
#include <string.h>
#include <deco_fill.h>
#include <test.h>
string st=ST_USE;
A::B::tStrict strictType=CnvStrToEnum(st);
setStrict(strictType);//I want here to use the setStrict methode to set a new variable of type enum with that. This part is not important
I have a compile error in test.cpp like ST_DEL, ST_USE and ST_UNKNOWN were not declared. What's do I need here and how can I correctly the string type in my enum type. Thanks for your help.

Answer 1

enum is for numeric constants (not strings), so you can't write
enum tStrict{
"ST_UNKNOWN"=-1;
"ST_USE"=0;
"ST_DEL"=1;
}
Also note it's comma (NOT semicolon) after each enum constant.
So instead you should write:
enum tStrict{
ST_UNKNOWN=-1,
ST_USE,
ST_DEL
};
Usually you can then convert enum constants to string counterparts:
const char *tStrictStr( const enum tStrict t )
{
switch( t )
{
case ST_UNKNOWN : return "ST_UNKNOWN" ;
case ST_USE : return "ST_USE" ;
case ST_DEL : return "ST_DEL" ;
default : return "ST_UNKNOWN" ;
}
}
