Format number to 2 decimal places

Truncate always "rounds" down. 1.999 truncated to 2 DP would be 1.99 where 2.00 would mathematically be more correct. If that's not a problem then truncate's fine but you should be aware of it.

You want to display each of these products with the title and formatted price. Let's try using toPrecision first:
document.write("The price of " + products[0].t...
How do I create an array of strings in C?
...th this approach is the possibility of internal fragmentation; if you have 99 strings that are 5 characters or less, but 1 string that's 20 characters long, 99 strings are going to have at least 15 unused characters; that's a waste of space.
Instead of using a 2-d array of char, you can store a 1-d...
“’” showing on page instead of “ ' ”
...you see that this character is in UTF-8 composed of bytes 0xE2, 0x80 and 0x99. If you check the CP-1252 code page layout, then you'll see that each of those bytes stand for the individual characters â, € and ™.

What generates the “text file busy” message in Unix?

}
Compile and run:
gcc -std=c99 -o sleep.out ./sleep.c
gcc -std=c99 -o busy.out ./busy.c
./sleep.out &
./busy.out
busy.out passes the asserts, and perror outputs:
Text file busy
so we deduce that the message is hardcoded in glibc itself.
