Is Python strongly typed?
...g access to the underlying representation. In C, I can create a pointer to characters, then tell the compiler I want to use it as a pointer to integers:
char sz[] = "abcdefg";
int *i = (int *)sz;
On a little-endian platform with 32-bit integers, this makes i into an array of the numbers 0x6463626...
How can I safely encode a string in Java to use as a filename?
...If collisions must be avoided, then simple replacement or removal of "bad" characters is not the answer either.
Instead you want something like this. (Note: this should be treated as an illustrative example, not something to copy and paste.)
char fileSep = '/'; // ... or do this portably.
char es...
Most efficient T-SQL way to pad a varchar on the left to a certain length?
...ng like
right('XXXXXXXXXXXX'+ rtrim(@str), @n)
where X is your padding character and @n is the number of characters in the resulting string (assuming you need the padding because you are dealing with a fixed length).
But as I said you should really avoid doing this in your database.

As an aside to what folks have been posting here, I've heard that concatenation can be much faster than join in modern javascript vms. Meaning:
var a =
[ "hey man, this is on a line",
"and this is on another",
"and this is on a third"
].join('\n');
Will be slower than:
var a = "hey...

What's the difference between a file descriptor and file pointer?

You'd certainly want the following to call the free function, don't you?
char const* s = "free foo!\n";
foo f;
f << s;
That's why member and non-member functions are include...

...ing puts.c source code
#include <stdio.h>
int main(int argc, const char *argv[])
{
while (*++argv) puts(*argv);
return 0;
}
It will not compile because argc is unused, and the settings are hardcore (-W -Wall -pedantic -Werror).
