std::putchar

int putchar( int ch );

Writes a character ch to stdout. Internally, the character is converted to unsigned char just before being written.

Equivalent to putc(ch, stdout).

Parameters

Return value

On success, returns the written character.

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

Example

#include <cstdio>
 
int main()
{
    for (char c = 'a'; c != 'z'; c++)
        std::putchar(c);
    std::putchar('\n');
 
    // 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);
}

abcdefghijklmnopqrstuvwxy
0x1070
