How to resize a terminal window from program in linux?

Question

I have fedora distro. The task is to write a simple console unicode game which would display correctly only on specific terminal window size, say 50x80 symbols.

Answer 1

You can resize the terminal before starting the game.
Running this command( requires xterm to be installed):
resize -s 50 80
will resize your terminal to 50x80 symbols.
Now you can write a simple shell script containing the above command and execute it or just directly execute by making system call in Cpp of any language.
