Help me make a c program that has a character array able to store a welcome message.

And an array with a float database to store the prices of the items.

Prompt the user to enter how many items they gave to total and create an array of that size.

Use a for loop to prompt and read the number of items.

You will need to pass the prices to a function to create and compute the total including the sum of the prices and a sales tax of $6\%.$

The function must use a acummaltaing total statement to compute the total sales.

The function must add the sales tax and return the total including tax to the main program.

The main progran outputs the grand total.

You must output the total before the tax before the output with the total with tax.
