std::putchar - cppreference.com (original) (raw)
| | | | | ---------------------- | | | | int putchar( int ch ); | | |
Writes a character ch to stdout. Internally, the character is converted to unsigned char just before being written.
Equivalent to std::putc(ch, stdout).
[edit] Parameters
| ch | - | character to be written |
|---|
[edit] Return value
On success, returns the written character.
On failure, returns EOF and sets the “error” indicator (see std::ferror()) on stdout.
[edit] Example
#include int main() { for (char c = 'a'; c != 'z'; ++c) std::putchar(c); // putchar return value is not equal to the argument int r = 0x1024; std::printf("\nr = 0x%x\n", r); r = std::putchar(r); std::printf("\nr = 0x%x\n", r); }
Possible output:
abcdefghijklmnopqrstuvwxy r = 0x1024 $ r = 0x24
