Centering on the screen

I was wondering if someone could help me with a program I am working on. I'm designing a C console application and I am trying to find a way to center text on the screen. so that it is in the middle from the top to the bottom and from left to right. Any ideas?

I won't supply you with the code, but will supply you with some math.


int column=center_of_screen_column-(textwidth_in_columns/2);
int row=center_of_screen_row-(textheight_in_rows/2);

Which version do you use
if it borland c
then
midx=getmaxx()/2;
midy=getmaxy()/2;
outtextxy(midx,midy,"text");
and u have to include graphics.h also.

I'm using .Net

You have to find the .net functions to get the size of the console window. Then, of course, follow planet_abhi's solution.

Won't work. It does not take into account the textheight or textwidth of text. The formulas I supplied are standard formulas for typing and layout and will center the text no matter how tall it is and no matter how wide it is, given that the text does fit into the dimensions of the window.

This works by centering the text across a line....you can modify it to move to the center of the screen vertically too...

Code:

---

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

#define TEXT_WIDTH  80

void centre(char[], int);

int main(void)
{
    char text[81];
   
    puts("Please enter a phrase:");
    gets(text);
    centre(text, TEXT_WIDTH);
   
    system("pause");
    return 0;
}


void centre(char text[], int width)
{
    char outtext[1+width];
    int n, len, pre;

    len = strlen(text);

    pre = (width - len) / 2;
    for (n=0; n < pre; n++) {
        outtext[n] = ' ';
        }

    outtext[pre] = '\0';

    strcat(outtext, text);

    for (n=len+pre; n < width; n++) {
            outtext[n] = ' ';
        }
    outtext[width] = '\0';
    printf("%s",outtext);
}

C89 (the most widely available version of C) doesn't allow variable length arrays.
You need C99 (the new C standard) or C++ to be able to do this.

HEY...

I just copy/pasted that code from one of my old archived C files....didnt even bother looking at it.... :)
