Question

In C-

I am creating a word jumble game and till now I have come up with a function that will jumble the letters of the word. I however also want to add a feature where in if the user needs help , the user can press a "1" and the the first letter of the jumbled word would be revealed so it could act as a clue.

For instance if the word is "swing" the jumbled word is "nsigw". So I want to create a function which if the user presses, will result in the output to be "snigw" because the first letter of swing is "s".

The code I currently have is -

void scramble(char *p, int len)

{

int i = 0;

while(i < len)

{

int c1 = (rand() % (len));

int c2 = (rand() % (len));

if(c1 != c2)

{

p[c1] = p[c1] ^ p[c2];

p[c2] = p[c1] ^ p[c2];

p[c1] = p[c1] ^ p[c2];

i++;

}

int main()

{

char word[] = "clay";

/* seed the randomizer */

srand( (unsigned)time(NULL) );

/* scramble the string */

printf("Original: %s\n", word);

scramble(word, strlen(word));

printf("Scrambled: %s\n", word);

return(0);

}

I need help in creating the other function
