How can a user input words?

[Ronon666]

Hey guys, im working on a program that you type a password and than you can proceed with the program but what do i type instead of int? (srry i forgot what the int was. i know its an integer but what was it.) coz with int,double you can put numbers, bool, true/false and with char only 1 char, but how do i insert a full word?

char passwd[50];
std::cin >> passwd;
If(passwd == "the actual pass"){
std::cout << "Access Granted”;
} else {
std::cout << "Access Denied";
}

This should work, but I haven't used C++ for like 2 months, so it might contain some small syntax errors. (I've been using Java lately).

isnt it with cin?
for example

int blabla;
cout << "This is a random line";
cin >> blabla;

Forgive me if im wrong.
I just started learning C++

int blabla;
cout << "This is a random line";
cin >> blabla;

Yup I learned this with cout<< for outputs and cin >> for user input.

But as I also changed to Java, maybe...

An int doesn't hold a word.
A array of chars or a string does.

O.o i created something like this (Just to try if the pw thing works) but when i run it and write kana it says access denied. plz help.

#include <iostream>
#include <Windows.h>

using namespace std;

int main()
{
	char passwd[50];
		cin >> passwd;
	if(passwd == "kana"){
		cout << "Access Granted";
	}else{
		cout << "Access Denied";
	}
}

Cookie thanks for correcting me .. i ve just started

[Auxilium]

#include <string>
then use std::string type

[Hell_Demon]

You can't compare two words like that, a char array is nothing but a pointer, seeing as the pointers to both strings will be different even if the text is the same, you'll have to use one of the following:

if(!strcmp(passwd, "kana") // strcmp returns 0 if both strings are the same
{
//code
}

Or:

if(std::string(passwd).Compare("kana"))
{
}

[wtfiwantthatname]

#include <iostream>
#include <string.h>
using namespace std;

int main()
{
	string passwd;
		cin >> passwd;
	if(passwd == "kana"){
		cout << "Access Granted";
	}else{
		cout << "Access Denied";
	}
}

If he has using namespace std; and #include <string.h> than he doesnt need to prefix std:: to all of his strings.

[Ronon666]

thx guys for your help.
#include <string.h> did not help at all btw.....

#include <string> did help but i tried it before... it didnt work than o.O.

#include <iostream>
#include <string>

using namespace std;

int main(){
	string acc, pw;
	cout << "Username: \n";
	cin >> acc;
	cout << "Password: \n";
	cin >> pw;
	if(acc == "MPGH"){
		cout << "Username correct\n\n";
	}
	else if(acc != "MPGH"){
		cout << "Username incorrect\n\n";
	}

	if(pw == "cplusplus"){
		cout << "Password correct\n\n";
	}
	else if(pw != "cplusplus"){
		cout << "Password incorrect\n\n";
	}
	if(acc != "MPGH" && pw != "cplusplus"){
		cout << "Username or/and password incorrect, are you sure you got the valid info?" << endl << "contact me for the password and username\n" << endl;
	}
	else if(acc == "MPGH" && pw == "cplusplus"){
		cout << "Information correct. Press any key to see your code." << endl;
		system("pause");
		cout << endl;
		cout << "Code : gHahwsejGKfndfj6893860339gDhbJeGhtdhzxvnG" << endl << "paste this on the forum\n\n";
	}
	system("pause");

}

That what i came up with and i think its pretty cool.
Now i need to find out somewhere what to use it for xD.

.-. Really simple:

#include<iostream>
#include<cstdlib>// to add Pauses, if u don't want them then erase em.
#include<string>
#include<windows.h>//I think u need this to erase everyting on the screen. //don't remember

using namespace std; // so u can just write cout instead of std::cout

int main()
{
   string username = "Guest"; // declare a string variable and initialize it.
   string password = "MPGH";
   string userInput1;
   string userInput2;

   int security;

// a string variable holds letters. Which in this case it's what you want

   cout << "username: ";
   cin >> userInput1;

   system("CLS"); // erases everything on the screen. 

   cout << "Password: ";
   cin >> userInput2;

   if(userInput1 == username)
   {
       security = 5;
       
       if(userInput 2 == password)
       {
       security = security + 5;


       }

   }
   else 
   {
   security = 0;

   }
   
   if(security == 10)
   {
      cout << "Welcome guest!\n\n";

   }
   if(security == 5)
   {
        cout << "incorrect password or username. Shutting down.\n";
        system("PAUSE");
        return 0;
   }
   if(security == 0)
   {
        cout << "error Shutting down\n\n";
        
        system("PAUSE");
        return 0;


   }

 system("PAUSE");
 return 0;
}

I think this should work. If it doesn't tell me. remember to #include<string>
if u don't it won't work.

oops. Didn't see your last post XD sry then

a error I saw. first u forgot one little curly brace at the end. and u put
system("pause"); instead of system("PAUSE");
and sudgestion, when u name functions try naming them so u remember what they're for. And so that your code is more readable to others. and something people tend to do is that the first word in a variable name starts with a none capital letter and the other words in a variable name are capital letters.
like this:

int aVariable = 100;

oh and if you name more than one variable by the same type, name them in different lines so it's more readable to others.

like this:

instead of:
int pie, cake;

try:
int pie;
int cake;

I think that's it

"system("CLS");" <------- DONT DO IT.

Couldn't word it well so here:
"It's frowned upon because it's a platform-specific hack that has nothing to do with actually learning programming, but instead to get around a feature of the IDE/OS - the console window launched from Visual Studio closes when the program has finished execution, and so the new user doesn't get to see the output of his new program."

[DecoderBack]

#include <string>
then use std::string type

it should be better if he uses using namespace std; into the top with includes hearders lol


for example

#include < blah blah my hearder>

using namespace std;


int main()

{
                      cout << "Hello my first message in output";
// output ( message )

			cin >> inicial >> final >> razao;

// input ( when the person enter something into the screen)


}

[Fovea]

That is absolutely incorrect. Polluting the global namespace (e.g., using namespace std;) is highly frowned upon. There is reason why the standard library is implemented within the std namespace.

If you MUST import names, do so in the most local scope possible using a using declaration, not a using directive.
