104. Strings and Character Handling-i

Question.7

A developer uses strncpy for a safe copy:

char buf[8];
strncpy(buf, "FIRMWARE_V2", sizeof(buf));
printf("%s", buf);

The source string (11 chars + \0) is longer than the buffer (8). What happens?

Need Help? Refer to the Quick Guide below

buf contains "FIRMWARE" with a null terminator — safe and correct
buf contains "FIRMWARE" without a null terminator — printf overreads memory
Compilation error — strncpy detects the size mismatch
buf is truncated to "FIRMWAR" with a null terminator at buf[7]
