Printf_tabell

In this example the program will print a table with 2 columns and 2 rows using the function "printf()".

You need to use a font with same width on all characters for it to look good.

I'll need to include these files

#include <stdlib.h>

#include <stdio.h>

I'll be making a simple console application with entry point "main()"

int main()

{

I'll be using these variables

char format[20];

char str1[10];

char str2[10];

Here I write a format string to hold the format of an entry in the table, one line. It will be 2 columns of 8 characters width.

sprintf_s(format, 20, "%c%ds %c%ds\n", '%', 8, '%', 8);

Here I give the test variables some value so I have something to write to the screen!

sprintf_s(str1, 10, "Hello!!");

sprintf_s(str2, 10, "World!!");

Now I print a row of the table using the format string

printf(format, str1, str2);

Now I give some new values for the next row

sprintf_s(str1, 10, "Hello");

sprintf_s(str2, 10, "World");

Printing row 2 to the screen

printf(format, str1, str2);

This is only to stop the program so you can see the output, press any key to continue

getchar();

}

Things that could be done:

¤ If you are using many strings, ex str_1, str_2, srt_3, ..., str_n, you could check the width on all the strings with "strlen()" and then take the highest value to be the column width.
