Defined in header <cstdio>
int fputc( int ch, FILE *stream ); int putc( int ch, FILE *stream );

Writes a character ch to the given output stream stream. putc() function may be implemented as a macro.

Internally, the character is converted to unsigned char just before being written.

Parameters

ch

-

character to be written

Return value

On success, returns the written character.

On failure, returns EOF and sets the error indicator (see ferror()) on stdout.

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, stdout);
    std::printf("\n0x%x\n", r);
}

Output:

abcdefghijklmnopqrstuvwxy
0x1070
p
0x70
