using arrays and functions

I need help passing an array to a function, and then getting corresponding soundex code. I am having problems passing the array to the function, and getting the array from the user. here is what I have done so far (with errors, which you guys will figure out right away). The main program asks the user for a word (which should be put in an array), and then gives the corresponding code. It does this 10 times. // This program accepts 10 words from the user and outputs the corresponding soundex code #include <iostream.h> #include <ctype.h> // code function takes in the word from the user and returns the soundex code for that word // input: a char array of the word from the user // output: nothing // return: a char array of the soundex code for that word char* code(char *array); // the main function takes a word from the user and calls the code function. It does this 10 times int main() { // a char variable for the word input by the user char word[30]; for (int i = 1; i < 11; ++i) { cout << "Please enter word number " << i << ": "; cin >> word; cout << endl; cout << "The soundex code for " << word << " is: " << code(word) << endl; } return 0; } char* code(char *arr) { // create the return array and set it to the default soundex code char rval[]= new char [30]; // create an array for the initial conversion char sound[30] = {0}; for (int i = 0; arr[i] != '\0'; ++i) { switch (tolower(i)) { case 'b': sound[i] = 1; break; case 'p': sound[i] = 1; break; case 'f': sound[i] = 1; break; case 'v': sound[i] = 1; break; case 'c': sound[i] = 2; break; case 's': sound[i] = 2; break; case 'k': sound[i] = 2; break; case 'g': sound[i] = 2; break; case 'j': sound[i] = 2; break; case 'q': sound[i] = 2; break; case 'x': sound[i] = 2; break; case 'z': sound[i] = 2; break; case 'd': sound[i] = 3; break; case 't': sound[i] = 3; break; case 'l': sound[i] = 4; break; case 'm': sound[i] = 5; break; case 'n': sound[i] = 5; break; case 'r': sound[i] = 6; break; default: sound[i] = '-'; break; } } if (isdigit(arr[0])) rval[0] = 'Z'; else rval[0] = toupper(arr[0]); for (int j = 1; sound[j] != '\0'; ++j) { if (sound[j] == '-') // break else if (sound[j] == sound[j-1]) // break else for (int k = 1; rval[k] != '\0'; ++k) { rval[k] = sound[j]; } } return rval; } Once I get this to work I will work on the function to get the soundex. I am getting errors right now about converting a char of one size to another char. Thanks for your help.
