Size of Terminal window

The classic size of terminal window is 25×80 (lines x columns), but you counting coordinates from 0.

And the whole communication with server (from start to end) must be set like this.

Hope it helps.

Hi, here is one program for calculating the number of rows and columns of your terminal window. Classic size is, like Ondrej said, 25x80, but mine has 30x120 so I hope this will be helpful.

#include <windows.h>

int main(int argc, char *argv[]) {
    CONSOLE_SCREEN_BUFFER_INFO csbi;
    int columns, rows;

    GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi);
    columns = csbi.srWindow.Right - csbi.srWindow.Left + 1;
    rows = csbi.srWindow.Bottom - csbi.srWindow.Top + 1;

    printf("columns: %d\n", columns);
    printf("rows: %d\n", rows);
    return 0;
}
