pointer notation

Oct 21st, 2007

I need help with this problem. I have written the code. The function main() stores the message in an array. What I need to figure out is how to have the function restaurant accept the message as an argument(which is named menu) and display the message using pointer notation *(menu+i) and also again with the *menu notation.
Should I use this or something similar ? ptr[0] = ptr[10]

int restaurant(char*);
int main() {

    char message[17] = { 'W', 'h', 'a', 't', 's', ' ', 'f', 'o', 'r',
            ' ', 'l', 'u', 'n', 'c', 'h', '?', '\0' };
    int i, *mPtr;

    restaurant(message);

    return 0;
}
int restaurant(char* menu) {
    
    return 0;
}

I see that your function is empty. What have you tried so far?

int restaurant(char* menu)
{   
    int i;
    char strcpy(char menu[], char message[]);
    {
        int i = 0;
        while (menu[i] != '\0')
        {
           menu[i] = message[i];
            i++;
        }
        menu[i] = '\0';
        return menu;
    
}

Basically, I am trying to copy the "message" to the "menu" and then display using the
*(menu+i) and *menu notation.
