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);

// 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
