  1. PONo Suitable Constructor, and an incompatible declaration error
    text
    copied!<p>My header file:</p> <pre><code>// Definition of class SunshineWeb that counts Product 1, Product 2 // and Product 3 retail prices.

mySunshineWeb.displayMessage(); mySunshineWeb.inputProducts(); mySunshineWeb.displayProductTotal(); } // end main </code></pre> <p>My second problem is with <code>SunshineWeb mySunshineWeb("Sunshine Web Store");</code>, where it underlines <code>Sunshine Web Store</code> and states:</p> <pre><code> Error: no suitable constructor exists to convert from "const char[19]" to "SunshineWeb" </code></pre> <p>Just beginning to learn C++ object orientation programming, and this is a program I wrote for class - what gives? I googled and went through my notes, but it doesn't help / solve this problem at all. What really bugs me most is the no suitable constructor part, as I can simply throw all Customer Name related functions out of the window, as I haven't even implemented it yet, seeing as I can't get it working ; but maybe there's something I'm missing. Either way... I need help! Please save my baby!</p> <p><strong>Edit</strong> : Thanks for the help, I've noticed my error and tried tweaking it like suggested, so my header file now looks like :</p> <pre><code>// Definition of class SunshineWeb that counts Product 1, Product 2 // and Product 3 retail prices. Refer to Project 2.cpp for member // functions. #include &lt;string&gt; // program uses C++ standard string class // SunshineWeb class definition class SunshineWeb { public: SunshineWeb( std::string ); // constructor initialises customer name void setCustomerName( std::string ); // function to get customer name std::string getCustomerName(); // function to retrieve customer name void displayMessage(); // displays a welcome message void inputProducts(); // inputs a number of products void displayProductTotal(); // total number of what products private: std::string CustomerName; // customer's name int Product1Count; int Product2Count; int Product3Count; }; // end of class SunshineWeb </code></pre> <p>This fixed the incompatible declaration error (a simple typo mistake) from earlier, and I'm not sure if it fixed the error with no suitable constructor, because while the nasty red underline is gone, I still can't run the program : I opened up the error list from Visual Studio 2010, I see a couple of errors:</p> <pre><code>Error 5 error C2065: 'mySunshineWeb' : undeclared identifier c:\users\user\documents\visual studio 2010\projects\project 2\project 2\sunshineweb.cpp 9 Error 7 error C2065: 'mySunshineWeb' : undeclared identifier c:\users\user\documents\visual studio 2010\projects\project 2\project 2\sunshineweb.cpp 10 Error 9 error C2065: 'mySunshineWeb' : undeclared identifier c:\users\user\documents\visual studio 2010\projects\project 2\project 2\sunshineweb.cpp 11 Error 2 error C2065: 'SunshineWeb' : undeclared identifier c:\users\user\documents\visual studio 2010\projects\project 2\project 2\sunshineweb.cpp 8 Error 3 error C2146: syntax error : missing ';' before identifier 'mySunshineWeb' c:\users\user\documents\visual studio 2010\projects\project 2\project 2\sunshineweb.cpp 8 Error 6 error C2228: left of '.displayMessage' must have class/struct/union c:\users\user\documents\visual studio 2010\projects\project 2\project 2\sunshineweb.cpp 9 Error 10 error C2228: left of '.displayProductTotal' must have class/struct/union c:\users\user\documents\visual studio 2010\projects\project 2\project 2\sunshineweb.cpp 11 Error 8 error C2228: left of '.inputProducts' must have class/struct/union c:\users\user\documents\visual studio 2010\projects\project 2\project 2\sunshineweb.cpp 10 Error 4 error C3861: 'mySunshineWeb': identifier not found c:\users\user\documents\visual studio 2010\projects\project 2\project 2\sunshineweb.cpp 8 Warning 1 warning C4627: '#include "SunshineWeb.h"': skipped when looking for precompiled header use c:\users\user\documents\visual studio 2010\projects\project 2\project 2\sunshineweb.cpp 3 </code></pre> <p>Yes, I am a complete amateur making (mostly) silly mistakes, but for the love of my life I can't seem to find a solution to my seemingly-simple problems. These problems makes no sense whatsoever, and I'm quadruple checking everything. Thanks for the help (and patience displayed), I really appreciate it.</p>
