3. n addition to the other answers which correctly point out that you are seeing undefined behavior, I figured I'd mention that std::cout uses an object of type std::streambuf to do its internal buffering. Basically it is an abstract class which represents of buffer (the size is particul...
intsnprintf(char*str,size_t size,constchar*restrict format,...) snprintfis guaranteed not to write more thansizebytes intostr, so use of it can help avoid the risk of a buffer overflow, as in the following code fragment:
printf("Printf buffer overflow!\n"); } if (c == '\n') { buff[buff_offset] = 0; buff_offset = 0; #ifdef __TURBOC__ _ES = FP_SEG(buff); _DX = FP_OFF(buff); _AX = 0x13; __int__(0xe6); #elif defined(I86) asm { push ds; pop es; mov dx, offset buff; mov ax...
In C, the standard functiongets()was removed in the latestC11standard. While this function can be used for string input, itshould be avoided at all costs. It is not a safe method for inputting strings because it writes to memory continuously as you type, making buffer overflows a common...
