how to change font size in c++ ?

I want to change font size on tc3.exe.

"hellow friends". for this, I should set font size 16.
"how are you".   for this, I should set font size 20.
" thank you ".  for this,I should set font size 25.

I want to set directly into hardware without using  ready made function in header files.

I want to write directly into hardware . for example  int86(0x10, &regs,&regs   ) function and 0xb8000000 is used to write directly  into monitor

There is no standard way to change fonts in C++, since C++ has no concept of fonts. You'll need to refer to the system api documentation for whatever platform you are developing for.

Did you see my comment above? This isn't something covered by the C++ standard. You need to refer to your system API documentation. Alternatively, if you tells us what system you are building for and what compiler you are using we can point you at the right documentation. I can also arrange to get this question moved into more apropriate zones as the zone assignments you've used are for generic C/C++, which this question is not.
