scanf("%[^\n]s", s); printf("%s\n", s); fflush(stdin); } return 0; } The code above takes a single input and gives the same result. The buffer is then cleaned using the fflush(stdin) function, and then the next input is entered and printed and so on. Output What Does fflu...

What does it mean to add one to a pointer? In C, it gives a pointer to the cell one farther on, which in this case is a[4]. To make this clear, let’s assign this new pointer to another pointer variable: ip2 = ip + 1; Now the picture looks like this: If we now do *ip...
scanf("%d", &bytes); memcpy(buf, in, bytes); …” Another scenario for buffer overflow is when data properties are not verified locally. The function ‘lccopy()’ takes a string and returns a heap-allocated copy with uppercase letters changed to lowercase. The function does not perform ...
