A. What does the following function do? Explain.

int guess(char string[])

{

int len = strlen(string);

int i;

char tmp;

for(i = 0; i < len / 2; i = i + 1)

{

tmp = string[i];

string[i] = string[len - i - 1];

string[len - i - 1] = tmp;

}

return 0;

}

B- Rewrite the function using pointers.
