String variables

[rottmanj]

I am new to oop c++ and I am trying to better educate myself on it. One issue that I have run into is how to store a string based variable.

Everything I have tried ends up with the errors below. Any information on this would be greatly appreciated.

DbConnect.h:7: error: ‘string’ does not name a type
DbConnect.h:8: error: ‘string’ has not been declared
DbConnect.h:9: error: ‘string’ does not name a type
DbConnect.cpp:5: error: variable or field ‘db_set’ declared void
DbConnect.cpp:5: error: ‘string’ was not declared in this scope
DbConnect.cpp:9: error: ‘string’ does not name a type
 

Here is my code.

DbConnect.h

#ifndef DBCONNECT_H_
#define DBCONNECT_H_
 
class DbConnect
{
public:
    string keep_value;                // private data value
    void db_set(string db_value);    // public method to set value
    string db_get(void);                    // public method to get value
};
 
#endif /*DBCONNECT_H_*/
 

DbConnect.cpp

#include "DbConnect.h"
#include <string>
 
 
void DbConnect::db_set(string db_value){
    keep_value = db_value;
}
 
string DbConnect::db_get(void){
    return (keep_value);
}

This is a namespacing issue. You need to either put "std::string" everywhere instead of just string or put "using namespace std" at the top of the file.

You also need to #include <string> in your .h file (any file that wants to use strings must #include <string> or include a file that does)
