Variables
I'm using VC+ 2010 Express. I didn't install anything else. I want to make console program which makes variable. Code:
1
2
3
4
5
6
7
8
9
10
11
12

#include <iostream>
#include <string>
string varName
string varValue
int main () {
cout << "Write in variable's name" << endl;
cin >> varName;
cout << "Write in variable's value" << endl;
cin >> varValue;
var varName = varValue;
}

Is something like this possible?
If you don't understand what i sayed please ask a question.
No, that's not possible. C++ is not a reflexive language.
Why do you want to do this?
While it's not possible as described by the OP, it's fairly easy to approximate it:
1
2
3
4
5
6
7
8
9
10
11
12
13
14

#include <iostream>
#include <string>
#include <cctype>

{

std::cout << it->first << ": " << it->second << '\n' ;
++it ;
}
}
int main()
{
map_type userVariables ;
addVars(userVariables) ;
printVars(userVariables) ;

Yeah, I was thinking of a map. That's why I asked the OP why they wanted to do this, to see if a map would be suitable.
