Changing the width of a Windows console window?

Im writing a simple brick breaker program. How do I maximize the console window, when the program starts.

Answer 1

Call the SetConsoleDisplayMode() function with the CONSOLE_FULLSCREEN_MODE flag.

[If you want to make the window maximise but not go into full screen mode then it is a lot more complicated because you have to calculate how many columns and rows will exactly fit the screen at the current screen resolution, taking into account the size of the window furniture (caption, scrollbars, borders). That isn’t a trivial task. See GetSystemMetrics(), EnumDisplayMonitors(), GetMonitorInfo(), SetConsoleScreenBufferSize(), etc.]
