Defined in header
Writes a character
ch to the given output 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.
|ch||-||character to be written|
 Return value
On success, returns the written character.
abcdefghijklmnopqrstuvwxy 0x1070 p 0x70
