std::fputc, std::putc - cppreference.com (original) (raw)
Writes a character ch to the given output stream stream.
Internally, the character is converted to unsigned char just before being written.
In C, putc() may be implemented as a macro, which is disallowed in C++. Therefore, calls to std::fputc() and std::putc() always have the same effect.
[edit] Parameters
| ch | - | character to be written |
|---|---|---|
| stream | - | output stream |
[edit] Return value
On success, returns the written character.
On failure, returns EOF and sets the error indicator (see std::ferror()) on stream.
[edit] Example
#include int main() { for (char c = 'a'; c != 'z'; c++) std::putc(c, stdout); // putchar's return value is not equal to the argument int r = 0x102A; std::printf("\nr = 0x%x\n", r); r = std::putchar(r); std::printf("\nr = 0x%x\n", r); }
Possible output:
abcdefghijklmnopqrstuvwxy r = 0x102A * r = 0x2A
