Please Help!!

When I input this code most of the classes come up as Calculus 1. The classes should differ depending on the course number. PLEASE HELP!!

Are you trying to compare a char with a c - string ?

[elite zero]

cin.get() will only get one character. If you type in: Chemistry, you'd get C only. Instead of using cin.get(), try a getline. For Example:

cout << "Please type in the course number: ";

getline( code, cin);     // Gets entire line of input

cout << endl;    // Line spacer before output 

Reference:

http://www.cplusplus.com/reference/string/string/getline/

[CCoder12]

I believe I am trying to use a string. How do I change the program for that?

[nvrmnd]

Declare code as char* code; to make it a c - string not a single char, then store the input by cin >> code;

and when you compare, you don't need dereference operator, just use the variable name:

A little example:

#include <iostream>
#include <cstring>

using namespace std;

int main()
{
   const char* myname = "nevermore";
   char* name;
   
   name = "nevermore";
   
   if ( name == myname ) cout << "Names matched !" << endl;
   else cout << "Didn't Matched !" << endl;
   
   return 0;
}

@nevermore28
When you provide suggestions make sure that you know what you're talking about.

Declare code as char* code; to make it a c - string not a single char, then store the input by cin >> code;

this will crash

A little example:

That compares pointer not the strings

@CCoder12
Using std::string would make it indeed much easier if it is allowed:

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


int _tmain(int argc, _TCHAR* argv[])
{
string code;

...

cout << "Please type in the course number: ";
cin >> code;

if (code == c1) // Note: no *
cout << "CHEMISTRY FOR ENGINEERS" << endl;

...


return 0;
}

@coder777 i admit i'm wrong with cin but why did my code worked ? i've use an online compiler

and why when i compare name with myname it worked, you said i was comparing pointers

Okay, i promise i will not post any code w/o actually testing it, sorry ...

The compiler you used generated the same pointer for the two strings. Other compiler might not.

Use strcmp() to compare (reliably) c strings:

http://www.cplusplus.com/reference/cstring/strcmp/?kw=strcmp

[nvrmnd]

Oh tnx, now i learned another thing: that assumption will not always work in the world of programming

[CCoder12]

Thank you everyone!

I changed the program to include the strings and it worked perfectly. I did have to take out the stars in front of the c.

The reason it wasn't working was that there was more than one character but it was only reading the first character.
