How to change the font size in a console application using C

How to change print font size with c?

 printf ("%c", map[x][y]);

I want to print an array more than all the other text in the program. Is there any way to make this conclusion larger?

Although teppic answer for use system()will work, quite intensively, to invoke an external program just for that. Regarding the response of David RF , it is hard-coded for a certain type of terminal (perhaps a terminal type with VT100 support) and will not support the actual user terminal type.

In C, you should use the terminfo features directly:

#include <term.h>

/* One-time initialization near the beginning of your program */
setupterm(NULL, STDOUT_FILENO, NULL);

/* Enter bold mode */
putp(enter_bold_mode);

printf("I am bold\n");

/* Turn it off! */
putp(exit_attribute_mode);

, teppic, . .

This code will work in Win32 applications (regardless of the subsystem used: WINDOWS or CONSOLE):

inline void setFontSize(int a, int b) 

{

    HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);

    PCONSOLE_FONT_INFOEX lpConsoleCurrentFontEx = new CONSOLE_FONT_INFOEX();

    lpConsoleCurrentFontEx->cbSize = sizeof(CONSOLE_FONT_INFOEX);

    GetCurrentConsoleFontEx(hStdOut, 0, lpConsoleCurrentFontEx);

    lpConsoleCurrentFontEx->dwFontSize.X = a;

    lpConsoleCurrentFontEx->dwFontSize.Y = b;

    SetCurrentConsoleFontEx(hStdOut, 0, lpConsoleCurrentFontEx);

}

Then just call (for example):

setFontSize(20,20);
0
