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 valueOn success, returns the written character.
On failure, returns EOF and sets the error indicator (see std::ferror()) on stream.
[edit] Example#include <cstdio>
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[edit] See also
