sprintf(szBuffe r, "%s %s %s", str1, str2, str3);

Sandy 4001 New York City

In your reference, review the section about length specifications that
can be used with the %s format specification.

Look in your C book. Also google for N869 or try the dinkum pages.

Meanwhile, don't toppost. Topposters make us mean and angry, and
we become most unpleasant.

Try %#s where # is the field width:
printf("%-10s%6d %-20s",
"Sandy", 4001, "New York City\n");

Look up in your C reference book the term
"format specifiers". If you don't have
a book get one. If your book doesn't have
this term in the index, get a different book.

I know "-" means left-aligned, "+" means right-aligned.
Does %-10s mean fixed 10 character spac, allocated for that string ?
I tried in my case sprintf(szBuffe r, "%-30s %s", str1, str2), but noticed
that if str1 is more than 12 char long, the str2 will not be aligned.
example:
TestingOut1 Hello
TestingOut123 World

No, "+" flag is not relevant for the %s conversion. "+" flag
make printf show the sign (+ or -). "-" flag means left justified,
while the default is right justified.

No. 10 means minimum field width.

"Characters from the array are written up to (but not including) the
terminating null character. If the precision is specified, no more than
that many characters are written."

Well, let see

C:\Temp>type test.c
#include <stdio.h>

int main( void )
{
printf("%-30s %s\n", "TestingOut 1", "Hello");
printf("%-30s %s\n", "TestingOut123" , "World");

return 0;
}

/out:test.exe
test.obj

C:\Temp>test

TestingOut123 World

which was displayed _exactly_ as expected. Perhaps try to watch
it in Courier font...
