...though.
Btw: If you're dealing with DNA strings only: You can compress a char into two bits and pack your data quite a lot. This will cut down the memory requirement by factor four over a naiive representation. Addressing becomes more complex, but the ALU of your CPU has lots of time to spend duri...
What is a reasonable length limit on person “Name” fields?
...put their information, including name. I gave the name field a limit of 50 characters to coincide with my database table where the field is varchar(50), but then I started to wonder.

Should I use encodeURI or encodeURIComponent for encoding URLs?
....
encodeURI assumes that the input is a complete URI that might have some characters which need encoding in it.
encodeURIComponent will encode everything with special meaning, so you use it for components of URIs such as
var world = "A string with symbols & characters that have special meanin...

IN objective-c, if you are dealing with regular char arrays (instead of pointers to NSString) you could also use:
printf("%.02f", your_float_var);
OTOH, if what you want is to store that value on a char array you could use:
sprintf(your_char_ptr, "%.02f", your_float_va...
Read file line by line using ifstream in C++
...d "token" you meant "delimiter". Right. With a comma, you'd say: int a, b; char c; while ((infile >> a >> c >> b) && (c == ','))

Do I cast the result of malloc?
...ther points are also trivial, if you use the variable in your malloc call: char **foo = malloc(3*sizeof(*foo)); if quite full-proof: 3 pointers to char pointers. then loop, and do foo[i] = calloc(101, sizeof(*(foo[i])));. Allocate array of 101 chars, neatly initialized to zeroes. No cast needed. cha...
What's best SQL datatype for storing JSON string?
...d as of SQL Server 2005 and should not be used for new development. Use VARCHAR(MAX) or NVARCHAR(MAX) instead
IMAGE, VARBINARY(MAX) : IMAGE is deprecated just like TEXT/NTEXT, and there's really no point in storing a text string into a binary column....
So that basically leaves VARCHAR(x) or NVARC...
What is the logic behind the “using” keyword in C++?
...::f; // lift Base's f into Derived's scope -- works in C++98

Derived(char); // provide a new constructor
