std::fputc, std::putc
From cppreference.com
| Defined in header <cstdio>
|
||
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.
Parameters
| ch | - | character to be written |
| stream | - | output stream |
Return value
On success, returns the written character.
On failure, returns EOF and sets the error indicator (see std::ferror()) on stream.
Example
Run this code
#include <cstdio> int main() { for (char c = 'a'; c != 'z'; c++) std::putc(c, stdout); std::putc('\n', stdout); // putchar return value is not equal to the argument int r = 0x1070; std::printf("\n0x%x\n", r); r = std::putchar(r); std::printf("\n0x%x\n", r); }
Output:
abcdefghijklmnopqrstuvwxy 0x1070 p 0x70
