    Exclamation Stdlib header help

    Can someone please tell me why I am getting this error. I included <stdlib> (Im using visual 2005 pro so .h is not needed), but im not sure what happened.

    c:\documents and settings\hp_administrator\my documents\visual studio 2005\projects\fire\fire\mainfire.cpp(2) : fatal error C1083: Cannot open include file: 'stdlib': No such file or directory

    P.s. I did attempt to add .h at the end and got 11 errors

    And as ALWAYS thanks

    having a different compiler/ide doesnt change the fact of having to include a .h file (for C) or not.

    look up the C++ standard library to find out what header files you need. most common one would probably be iostream.

    The proper way to include that librairy is to include <cstdlib>.

    The 11 errors you get after including it are probably not related, but did not surface before because you were not getting that far in compiling your programs before (the compiler bailed out before it found them).
    It is too clear and so it is hard to see.
    A dunce once searched for fire with a lighted lantern.
    Had he known what fire was,
    He could have cooked his rice much sooner.

    That's great, but that gives us basically zero information. Why don't you start with posting line 5 of mainfire.cpp?

    Here is a little bit:

    insert
    Code:
    #include<iostream>
    #include<string>
    #include<cstdlib>
    #include<windows.h>
    string name;
    string password;
    int selection;
    int report();
    int fire();
    using namespace std;
    
    int main()
    { 
    	cout << "Welcome to the Madigan Software Group Emergency Service" << endl;
    	cout << endl;
    	cout << "Please enter your login information" << endl;
    	cout << "User Name: "; cin >> name;
    	cout << "Password: "; cin >> password;
    	if (name=="madigansoftware" && password=="madigansoftware")
    	{
    		report();
    		return 0;
    	}

    If you're using string from the std namespace, don't you think your using statement should come first?
    Code:
    #include<iostream>
    #include<string>
    #include<cstdlib>
    #include<windows.h>
    string name;
    string password;
    int selection;
    int report();
    int fire();
    using namespace std;
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    Better yet, shift those global variables into say, main(), such that they become local variables.
