How can you count the number of characters entered into a variable... example int x; cin>>x; how can i count how many characters are in the variable i guess is what i''m asking.

You can''t really count them if you are using an int value. An int value is a (normally) 32-bit value and is going to be the same size no matter what. All you can do is look at the value.

If you read your input into a string that would be a different story. You could do:

cin >> mystring;

int numchars = strlen( mystring );

lol but to be honest I never really learned about the stream operators in C++ so I don''t know that cin >> mystring is really a valid operation. Sorry if not. lol

You could create a string of the integer, and then count the number of characters in the string:

#include <iostream>#include <sstream>#include <string>using namespace std;int main(){	int x;	cout << "x: ";	if (cin  >> x)	{		ostringstream s;		s << x;		string::size_type num_len = s.str().size();		cout << num_len;	}	else	{		cerr << "Please input a number!\n";	}	return 0;}
