You can change the font size using SetCurrentConsoleFontEx.
Below is a small example that you can play around with, make sure you #include <cwchar>and #include <windows.h>
您可以使用 更改字体大小SetCurrentConsoleFontEx。
下面是一个你可以玩的小例子，确保你#include <cwchar>和#include <windows.h>
CONSOLE_FONT_INFOEX cfi;
cfi.cbSize = sizeof(cfi);
cfi.nFont = 0;
cfi.dwFontSize.X = 0; // Width of each character in the font
cfi.dwFontSize.Y = 24; // Height
cfi.FontFamily = FF_DONTCARE;
cfi.FontWeight = FW_NORMAL;
std::wcscpy(cfi.FaceName, L"Consolas"); // Choose your font
SetCurrentConsoleFontEx(GetStdHandle(STD_OUTPUT_HANDLE), FALSE, &cfi);
std::cout << "Font: Consolas, Size: 24\n";

如果您选择Arial或其他字体，您可能需要为其指定字体大小宽度。欲了解更多信息。
