Only Detect Text in Quotations (C++)

Question

I'm not great at programming and recently started to read tutorials on C++.

I decided I would attempt to make a simple blackjack program. I tried to make a title with "big text" but C++ is preventing me from doing it because it is detecting other things inside the text.

    //Start Screen Begin
cout << " ____  _            _     _            _        ";
cout << "| __ )| | __ _  ___| | __(_) __ _  ___| | __    ";
cout << "|  _ \| |/ _` |/ __| |/ /| |/ _` |/ __| |/ /    ";
cout << "| |_) | | (_| | (__|   < | | (_| | (__|   <     ";
cout << "|____/|_|\__,_|\___|_|\_\/ |\__,_|\___|_|\_\    ";
cout << "                       |__/                     ";
    //Start Screen End

This is what I am trying to display, yet keep getting the following error:

undefined reference to 'WinMain@16'

I am asking if there is a way to tell C++ I only want it to read and display the text, and not use any functions.

That's a better job for C++11 raw string literals than escaping \ with \\:

#include <iostream>

int main() {
    using namespace std;
    //Start Screen Begin
    cout << R"( ____  _            _     _            _        )" << '\n';
    cout << R"(| __ )| | __ _  ___| | __(_) __ _  ___| | __    )" << '\n';
    cout << R"(|  _ \| |/ _` |/ __| |/ /| |/ _` |/ __| |/ /    )" << '\n';
    cout << R"(| |_) | | (_| | (__|   < | | (_| | (__|   <     )" << '\n';
    cout << R"(|____/|_|\__,_|\___|_|\_\/ |\__,_|\___|_|\_\    )" << '\n';
    cout << R"(                       |__/                     )" << '\n';
    //Start Screen End
}

Check the output here that it works for a decent compiler that support C++11: http://coliru.stacked-crooked.com/a/964b0d2b8bde8b3d

The following would also work:

#include <iostream>

int main() {
    using namespace std;

    //Start Screen Begin
    cout << 
R"(
 ____  _            _     _            _    
| __ )| | __ _  ___| | __(_) __ _  ___| | __
|  _ \| |/ _` |/ __| |/ /| |/ _` |/ __| |/ /
| |_) | | (_| | (__|   < | | (_| | (__|   < 
|____/|_|\__,_|\___|_|\_\/ |\__,_|\___|_|\_\
                       |__/                 
)";
    //Start Screen End
}

Your second-to-last text literal has several \ characters in it. That is an escape character, so to use the literal \ character you have to escape it as \\, eg:

cout << "|____/|_|\\__,_|\\___|_|\\_\\/ |\\__,_|\\___|_|\\_\\    ";

It won't look as good in code, but it will look fine when the app is run.

As for the reference error, WinMain() is the entry point for GUI apps, whereas main() is the entry point for console apps, so it sounds like you did not create/configure your project correctly if it is trying to link to WinMain() instead of main().

Answer 3

You'll need to escape the backslashes, instead of one \ have two \\.

These are used to indicate special characters like "\n" (line-break) appearing within a string literal ("..."). Your Big-Text misses all of those line-breaks BTW.

undefined reference to 'WinMain@16'

Apparently you are trying to compile a GUI project. Check your Code Blocks project type.
