Int wert in String umwandeln, aber wie?

[fluchtpunkt]

itoa(int a, char* b, in len);

nein.

char* itoa ( int __val,
char * __s,
int __radix
)
Convert an integer to a string.

The function itoa() converts the integer value from val into an ASCII representation that will be stored under s. The caller is responsible for providing sufficient storage in s.

Note:
The minimal size of the buffer s depends on the choice of radix. For example, if the radix is 2 (binary), you need to supply a buffer with a minimal length of 8 * sizeof (int) + 1 characters, i.e. one character for each bit plus one for the string terminator. Using a larger radix will require a smaller minimal buffer size.
Warning:
If the buffer is too small, you risk a buffer overflow.
Conversion is done using the radix as base, which may be a number between 2 (binary conversion) and up to 36. If radix is greater than 10, the next digit after '9' will be the letter 'a'.

If radix is 10 and val is negative, a minus sign will be prepended.

radix ist uebrigens englisch und heisst Basis, bei radix 10 befindet man sich also im Dezimalsystem.
