    My name program (need help)

    I am really new to c++ & have a question about my code.
    I am tryin to get this password checker to work but I cant get it to run correctly.

    Code:
    #include <iostream.h>
    int program();
    int main()
    {
    	char name[20];
    	cout << "            Input name for identification." << endl;
    
    	cin >> name;
    
    	if (name != "tim")
    	{
    	cout << "                 Name not Registered." << endl;
    	return 0;
    	}
    	else {
    		if (name == "tim")
    	program();
    	}
    
    	return 0;
    }
    int program()
    { 
    	cout << "            Welcome To the Restricted Zone." << endl;
    	
    	return 0;
    }
    
    /* I get no errors but it does not run how I want it to. No matter what I
    put in it still sends back "Name not Registered". Does anyone see the 
    problem? Any help is gladly appreciated thanks!*/

    You need to use strcmp( ) to compare char arrays. Also, you don't need the else if, just else.
    Code:
    if( strcmp( name, "tim" ) != 0 )
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    Use
    #include <string.h>

    To get the prototype for strcmp()

    > int strcmp();
    This zero-parameter version is no good
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
