Extended Types Formatted I/O (C++)
Go Up to Functions Index (C++)
The following table shows new format specifiers implemented in C++Builder for the printf and scanf family of functions. This implementation allows the input and output of 64-bit integers and provides greater I/O flexibility for other types.
| Format Character | Functionality |
|---|---|
|
%Ld |
__int64 |
|
%I8d |
8-bit wide integer (char) |
|
%I16d |
16-bit wide integer (short) |
|
%I32d |
32-bit wide integer (long) |
|
%I64d |
64-bit wide integer (__int64) |
Note that the above table uses the %d format as an example. The I8, I16, I32, I64 prefixes can be used with the d, i, o, x, X formats, as well as the new L prefix previously allowed only on float to specify long double type.
