For what value of i

, read from the input in the following code fragment, is there a buffer overflow?

int a[] = { 1, 3, 2, 0 };
int i; 
cin >> i;
a[a[i] + 1] = a[i];

Consider a C++ function of the form:

int f(const int a[], int b[]) {
   int c[] { 0, 1, 2 };
   // ...
   return c[0] + c[1] + c[2];
}

Which of the following possibilities to complete the code of f is valid (does not cause a compilation error) after the declaration of c and before the return

instruction?

Consider (as usual in 64-bit machines) that values of type long, int, and char

are represented using 8, 4, and 1 bytes in memory, respectively.

How many bytes are required for the representation of v

shown in the code fragment below (assuming no padding)?

struct data {
   long a;
   int  b[3];
   char c[12]; 
};
data v[4];

What is the output of the following code fragment?

struct data {
   int i;
   int j; 
   int v;
}; 
data d[3] { {0, 1, 2}, {3, 2, 1}, {0, 1, 2} };
std::cout << d[2].j << ' ' << d[d[0].v].i << ' ' << d[d[1].j].v << '\n';

What is the output of the following code fragment?

char s[] = "C/C++ is fun!";
int i = 0;
while (s[i] != '\0' && s[i] != ' ') i++;
s[i] = '\0';
std::cout << i << ' ' << s << '\n';
