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 unsignedchar 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 argumentint 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
