Can anyone help me in printing the string aligned to center in C?
For example:
int main()
{
int a = 20;
char x[10] = "Hello";
char y[10] = "Hello";
printf ("%*s\n",a, x );
printf ("%-*s\n",a,y);
}
In the above the first prints Hello aligned to the right and the second printf to the left like this
Hello
Hello
restricting the length for each to 20.
Is there a way to print Hello aligned to the center.
Hello
restricting the total length to 20.
Thankyou in advance
In general, you probably want to avoid centre-aligned text, especially on a console, but in any case; this will take some doing.
The (likely) reason that printf doesn't know how to do this to begin with is that it's not an entirely deterministic operation; not all strings can be centred in all spaces.
Notably, unless space_for_string - strlen(string) is an even number, you're going to have to make a choice regarding where you want the string to be shifted to.
In any case, you do want to use the "%*s"specifier, but the number you feed into the width field can't be as simple as a flat 20.
Instead you want to feed it half the width of your space plus half the width of your string.
int main()
{
int space = 20;
char *string = "Hello";
printf ("%*s\n", space / 2 + strlen(string) / 2,string);
}
