Dec 2, 2022 · The putc routine writes the single character c to the output stream at the current position. Any integer can be passed to putc, but only the lower 8 bits are written.

The C library putc () function writes a character (an unsigned char) specified by the argument char to the specified stream and advances the position indicator for the stream.

putc and fputc are equivalent, except that putc may be implemented as a macro in some libraries. See putchar for a similar function that writes directly to stdout.

Oct 4, 2023 · Writes a character ch to the given output stream stream. putc() may be implemented as a macro and evaluate stream more than once, so the corresponding argument should …

The putc () function converts c to unsigned char and then writes c to the output stream at the current position. The putchar () is equivalent to putc (c, stdout).

The putc () function in C writes a character to the specified stream and advances the stream's internal position indicator.

Apr 6, 2025 · This tutorial has explored the fputc and putc functions in C, demonstrating their usage through practical examples. These functions provide essential character-level output …

putc () is equivalent to fputc () except that it may be implemented as a macro which evaluates stream more than once.

The putc () function shall be equivalent to fputc (), except that if it is implemented as a macro it may evaluate stream more than once, so the argument should never be an expression with …

The putc () function is a C library function, which is used to write a character to a file. This function is used to write a single character to the stream as well as advance the position of the …
