std::fputc,std::putc(3) | C++ Standard Libary | std::fputc,std::putc(3) |
NAME¶
std::fputc,std::putc - std::fputc,std::putc
Synopsis¶
Defined in header <cstdio>
int fputc( int ch, std::FILE* stream );
int putc( int ch, std::FILE* stream );
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
