Class/Type: Writer

Method/Function: String

Examples at hotexamples.com: 24

C++ has a built-in string class called "std::string" which can be used for creating and manipulating strings. Below are a few examples of how to use the writer string in C++:

1. Example of Writing a String to Console:

#include 
using namespace std;

int main() {
    string str = "Hello World!";
    cout << str << endl;
    return 0;
}

This example shows how to declare a string variable, assign a value to it, and then write that string to the console.

Package library: Standard Library

2. Example of Writing a String to a File:

#include 
#include 
using namespace std;

int main() {
    string str = "This is a text file demonstration in C++";
    ofstream myfile;
    myfile.open("example.txt");
    myfile << str;
    myfile.close();
    return 0;
}

This example shows how to declare a string variable, open a file, write the string to the file, and then close the file.

Package library: Standard Library

3. Example of Writing a String to a Windows Textbox:

#include 

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
    LPSTR lpCmdLine, int nCmdShow) {

    HWND hwnd;
    MSG Msg;
    WNDCLASS wcl;

    wcl.hInstance = hInstance;
    wcl.lpszClassName = TEXT("Edit control");
    wcl.lpfnWndProc = WndProc;
    wcl.style = 0;

    RegisterClass(&wcl);
    hwnd = CreateWindow(wcl.lpszClassName, TEXT("Edit Control"),
        WS_SYSMENU | WS_VISIBLE, 50, 50, 400, 200, NULL, NULL,
        hInstance, NULL);

    string str = "This is a text string in C++";
    LPCSTR lpszText = str.c_str();
    SetWindowText(hwnd, lpszText);

    while (GetMessage(&Msg, NULL, 0, 0)) {
        TranslateMessage(&Msg);
        DispatchMessage(&Msg);
    }

    return Msg.wParam;
}

LRESULT CALLBACK WndProc(HWND hwnd, UINT message,
    WPARAM wParam, LPARAM lParam) {

    switch (message) {

    case WM_DESTROY:
        PostQuitMessage(0);
        break;

    default:
        return DefWindowProc(hwnd, message, wParam, lParam);
    }

    return 0;
}

This example shows how to declare a string variable and then use it to set the text of a Windows textbox. Package library: Windows API.
