# fputc, putc

From cppreference.com
< c‎ | io

Defined in header `<stdio.h>` |  |

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.

### [edit] Parameters

ch | - | character to be written

### [edit] Return value

On success, returns the written character.

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

### [edit] Example

Run this code

    #include <stdio.h>

    int main()
    {
        for (char c = 'a'; c != 'z'; c++)
            putc(c, stdout);
        putc('\n', stdout);

        // putchar return value is not equal to the argument
        int r = 0x1070;
        printf("\n0x%x\n", r);
        r = putchar(r, stdout);
        printf("\n0x%x\n", r);
    }

Output:

    abcdefghijklmnopqrstuvwxy
    0x1070
    p
    0x70
