#include
using namespace std;

// constants for maximum width and character symbols
const unsigned int max_width = 120;
char background_char = '.';
char main_char = '*';
char main_char_left = '/';
char main_char_right = '\\';

// function prototype declarations
void fillArray(char fill, char chArray[], unsigned int width);
void printArray(const char chArray[], const unsigned int width);

int main() {
unsigned int user_input;

// prompting the user to enter the width of the diamond
cout << "Enter width of diamond: ";
cin >> user_input;

// checking if user input is greater than the maximum width
if (user_input > max_width) {
// displaying an error message and exit with an error code
cout << "Enter width of diamond: " << user_input << endl;
cout << "Max width is " << max_width << "." << endl;
return 1;
} else {
cout << "Enter width of diamond: Error! Max width is " << max_width << " . Exiting." << endl;
}

// adjusting width for even numbers (make it odd)
if (user_input % 2 == 0) {
user_input--;
}

// declaring and initializing a 2D array to store the diamond pattern
char diamond[100][100]; // Use a sufficiently large array size

// filling the array with background characters
for (int i = 0; i < user_input; i++) {
fillArray(background_char, diamond[i], user_input);
}

// output the diamond pattern
for (int i = 0; i < user_input; i++) {
printArray(diamond[i], user_input);
cout << endl;
}

return 0;
}

// function to fill an array with the specified character
void fillArray(char fill, char chArray[], unsigned int width) {
for (unsigned int i = 0; i < width; i++) {

}
}

// function to print the array
void printArray(const char chArray[], const unsigned int width) {
for (unsigned int i = 0; i < width; i++) {
cout << chArray[i];
